OTTOPO T-handle Truck Cap Lock Replacement Set — T311 Left & Right, Keyed-Alike, Matte-Black Zinc Alloy for LEER-style Camper Shel

OTTOPO’s T311-style T-handle lock replacement set provides both left- and right-hand keyed-alike locks engineered to fit many LEER and similar truck caps and camper shells.

If your topper’s original T-handle locks are worn, corroded, or missing, this replacement pair gives you a straightforward path back to secure, weather-resistant closures. The kit includes two T-handles (one clockwise, one counter-clockwise), matching rods and bars, four keys keyed alike, mounting screws, and cam plate spacers. Constructed from zinc alloy and zinc-plated steel with a matte black finish, these components are designed to resist outdoor exposure while restoring functionality to pickup toppers, camper shells, and tonneau-associated doors.

Will these T311 locks fit my LEER or other camper shell?

These are made to replace T311-style dual T-handle locks used on many LEER, A.R.E., Century, Ranch, Jason, Astro and other brands, but accurate fit depends on your existing hole dimensions. The center mounting hole for T311 is larger than some T323 variants, so you must measure before ordering.

• Center hole must be larger than 5/8" (≈16 mm).
• Two side mounting holes should be larger than 8.2 mm.
• Mounting lugs spaced 1.5" apart and 3/8" deep.
• If holes are smaller, simple enlargement or filing may be required.

How do I install the OTTOPO T-handle replacement set?

Installation is intended to be a do-it-yourself task and typically requires only basic hand tools. The locks mount from the inside of the door using three pre-drilled holes; after aligning the cam plate and lock rod, secure with the included screws and test action before final tightening.

• Mount locks on the inside of the topper or shell door.
• Use the included screws and cam plate spacers for alignment.
• Verify rod and bar engagement length (rod 2", bar 2-3/4").
• Test keyed-alike operation before sealing or reassembling trim.

What materials and durability can I expect from these replacement parts?

The lock housings are die-cast zinc alloy finished with matte black powder coat to limit corrosion and provide a secure grip. Internal rods and cam bars are zinc-plated steel for strength, so the set stands up better to weather exposure than basic plated hardware.

• Zinc alloy lock body with matte-black powder coat exterior.
• Zinc-plated steel lock rod and bar for improved rigidity.
• Corrosion-resistant design for outdoor application.
• Four identical keys included to avoid mismatched locks.

What should I check before purchasing to avoid fitment issues?

Measure the existing lock openings and mounting spacing to confirm compatibility with T311-style dimensions. Review the product dimension diagram (see product images) and compare rod and cam bar lengths to the originals on your shell; mismatches are the most common source of fit issues.

• Confirm center hole diameter is at least 5/8" (16 mm).
• Check side hole diameter exceeds 8.2 mm.
• Compare mounting lug spacing (1.5") and depth (3/8").
• Match lock rod (2") and lock bar (2-3/4") lengths to your application.

Who is this for: This OTTOPO replacement kit is aimed at truck owners, DIY mechanics, and service technicians who need to replace worn or missing T311-style T-handle locks on camper shells, LEER-style toppers, and similar pickup caps. It’s ideal for anyone who wants keyed-alike convenience, corrosion-resistant hardware, and a practical, installable solution without replacing the entire shell or ordering dealer-only parts.
