Bicycle Locker Installation Information

Bicycle Lockers ABSC-300 Series – No Assembly Required

Your ABSC-300 series lockers (models 302, 301, 301P & 301V) do not require any general assembly.

If you ordered the optional number plates those may need to be installed.

Tools Needed:

Minimum requirements:

  • 3/8″ electric drill (anchoring & installing diagonal divider wall)
  • 3/8″ electric rotary hammer drill (anchoring)
  • 1/4″ drill bit (anchoring & installing diagonal divider wall)
  • 1/4″ hammer drill bit (anchoring)
  • hammer (anchoring)
  • Tape measure- minimum 10′ (anchoring & installing diagonal divider wall)
  • Extension cord 25′ (anchoring & installing diagonal divider wall)
  • Generator or other source of power (anchoring & installing diagonal divider wall)
  • Safety glasses and any other equipment specified by the tool manufacturer. (All Steps)

Choose location which allows a minimum 4′ distance between door face and any obstruction to allow bicycle to maneuver into locker and the door to swing open without hitting high spots such as concrete or asphalt raised by roots. If desired, for grouping of units, chalk a line for straight edge with which to work. A preferred site would be concrete although asphalt can be used. Site should be flat although it does not necessarily have to be level.


The lockers should be anchored to the ground for optimum longevity and proper operation of the locking system. Therefore, anchoring each unit to the ground is advisable. The 301 and 302 lockers are anchored in the 4 corners of the flange located around the inside of locker, the 301P, & 301V are anchored in the front two corner s of the locker and the rear. First square the doors in the frame. Out of square doors are due to the site being uneven. To square the door, using a flat bar, raise the corner of the locker to make the door in square. If any adjustment is necessary it should only be slight. Place a shim under the corner to retain the alignment and height. Shim should be placed in a location under the base flange very close to hole for the anchor. This allows the downward force of the anchor to be supported underneath and prevent cracking of the base flange at the anchor location. Drill through the base flange on the locker with 1/4″ drill. With hammer drill and 1/4″ masonry bit you can then drill into concrete surface. Drop the nail-in anchor through flange and into the hole, pound pin down flush with top of mushroom head of anchor. Do this at all four corners of door frame on 301 & 302 lockers. On 301P and 301V do this in the front two corners of the door frame and in center of rear wall.


A tube of silicone adhesive has been provided with your lockers. Place about 3/16″ bead of silicone on the back of the plate 1/4″ in from the edge. Center the number plate in recessed area on door and press firmly in place. You may want to use a piece of masking tape to hold the number plate in place for an hour or so to allow adhesive to partially dry. Do not leave masking tape on overnight or adhesive residue may be stuck on door when you remove the tape.

Bicycle Lockers ABSC-350 Series – Assembly Required

The purpose of this manual is to give step by step instructions on how install the model 352

Tools Needed:

Minimum requirements:

  • Claw hammer
  • 7/16” wrench open end
  • 7/16” socket (deep style) & ratchet
  • 3/8” electric drill
  • 3/8” electric rotary hammer drill
  • 1/4” drill bit
  • 3/8 hammer drill bit
  • Tape measure – minimum 10’
  • Extension cord long enough to reach power source & move around locker site
  • Generator, or other power source
  • Safety glasses and any other equipment specified by the tool manufacturer

Choose location which allows a minimum 4’ distance between the door face and any obstruction to allow bicycle to maneuver into locker. The door must be able to swing open without hitting high spots, such as concrete or asphalt raised by roots. If desired, for groups of units, use chalk to make straight edge lines to work with. Site should be concrete, although asphalt can be used. Site should be flat, although it does not have to be level.

Step 1:

If your locker doors are pre-numbered you will want to verify they are installed in a sequential order. Place the door frames, with the doors open, approximately 60″ apart measuring from flange to flange of both. This will let you slide the exterior walls and/or interior common walls into position on both door frames at the same time. (Interior common walls will be labeled with a sticker.) Once the walls are in place, insert 1/4” x 1″ hex head bolts and washers through the predrilled holes in the exterior walls and/or interior common walls to holes in the door frames. Tighten down the bolts with the nuts, around the door frames and walls. Only hand-tighten the bolts down at this time. This will hold the parts in place in order to do the next steps. If you are using interior common walls to attach two or more lockers, proceed to Step 2. If not, proceed to Step 3.

Step 2:

If you are joining two or more lockers in a group you will now need to follow these instructions. First, install the L-Brackets to the flange of the next door frame using 1/4” x 1” hex head bolts, washers and nuts. Put the next door frame and L-Bracket beside the existing door frame that was just assembled. Making sure both door frames line up (front to back, top to bottom), drill and bolt the opposite side of the bracket onto the finished side of the interior common wall. Once the L-Brackets are installed and HAND TIGHTENED to the interior common wall, follow Step 1 to attach the second door frame and exterior wall, or interior common wall, using the hardware provided.

Step 3:

To install the top, using two or more people, take the top and place it between the two door frames. Second, line up all bolt holes of the top, walls, and door frames. Place 1/4” x 1” hex head bolts through pre-drilled holes and attach washer and nut. Outer surfaces should be even where all parts come together. Make sure they are even. You can now tighten bolts installed in Steps 1, 2 and 3.

*When using grouped units, after the top is tightened down to the door frames, mount the L-Bracket to the top where you would connect the top to the interior common wall, using the 1/4” x 1” hex head bolts through pre-drilled holes and attach washer and nut. Tighten down L-Bracket to top, and then drill holes through L-Bracket and interior common wall. Using the 1/4” x 1 ” hex head bolts, tighten the L-Bracket to the interior common wall. Repeat for all interior common walls.

Step 4:

After the lockers are assembled they will need to be anchored to the ground at all four corners of the frame. The units have adjustable anchor brackets in order to level the units. Once the locker is in place and lined up where you want it, loosen the nuts on the bolts of the anchor bracket. This requires a 7/16″ end wrench or socket to loosen and/or tighten the nuts and bolts. After nuts are loosened, slide anchor bracket down, and at the same time using a flat bar, bring locker(s) into a level position and tighten the nuts. Do this for all four corners. This is usually a very slight adjustment. The locker, if necessary, can be raised up to 1″ with these brackets. After locker is level, drill a 3/8″ x 2″ deep hole through the bracket and into the mounting surface. Hint: Place a piece of tape around the drill bit 2” from the tip of the bit. When you drill, pay attention to the piece of tape. Stop drilling once the tape is no longer visible. Insert the washer and anchor into the drilled hole and using a hammer and punch, hammer the anchor into the mounting surface.

Step 5:

To install the interior diagonal wall(s) follow this step. Slide the wall through one of the door frames at an angle as seen in Figure 1. (This angle is the easiest way to install the diagonal.) The diagonal wall should be installed onto the left side of the door frame and must be attached to the angled lip of the door frame. Next, drill two ¼” holes 8” from the top and 8” from the bottom through both the diagonal wall, and the angled lip of the door frame. Bolt the door frame and diagonal together with ¼” x 1 ¼” hex head bolts, washers and nuts.

Step 6:

If you are assembling and installing any more units, simply repeat Steps 1-5.

Stacking Instructions

Tools Needed:

Minimum requirements:

  • 1/4” – 20 x 1” Carriage Bolts 8 per unit
  • 1/4” – 20 Hex Nuts 8 per unit
  • 1/4” Flat Washers 8 per unit
  • Tools needed:
  • Drill
  • 1/4” Drill bit
  • 7/16” Wrench

1. Before starting this step, you should have all of your ground level lockers anchored and bolted together so they do not move or change door alignment.

2. With 2 or more people, starting at one end of the grouping of lockers, lift the first unit in place and set on top of the ground level locker. Position the upper unit so that it lines up with the locker unit. With this done, you will now need to drill 1/4” holes through the base flange in the upper units and through the roof of the ground level units. See diagram below for general locations. We recommend following the sequence of drilling and bolting as indicated in the diagram so that the upper unit does not shift during the drilling process. Carriage bolts should be installed downward through the flange and locker top. Washers and nuts will be inside the ground level lockers. Tighten the nuts so they are snug.

3. Continue this process with each of the upper units.
