OTTOPO T-Handle Replacement Locks T311 Pair — Keyed-Alike, Matte Black Left & Right for Camper Shells

OTTOPO T311-style T-handle replacement locks supply both left- and right-hand keyed-alike locks engineered to replace worn or missing camper shell/topper locks on select LEER and similar truck caps.

These replacement parts are a direct-fit solution for many truck caps, toppers and camper shells that use the larger T311-style center mounting hole. The pair arrives with matching keys, zinc-alloy bodies and zinc-plated locking rods built to endure outdoor use. Review the fitment notes and measurements before purchase to confirm compatibility with your cap’s pre-drilled holes.

How do I know if the OTTOPO T311 lock fits my truck cap?

Measure your existing T-handle opening before ordering. The T311-style requires a larger center mounting hole than some other styles, so exact diameter checks prevent surprises during installation.

• Required center hole: larger than 5/8 inch (≈16 mm).
• Two side mounting holes: larger than 8.2 mm each.
• Mounting lug spacing: 1.5" apart, 3/8" deep; confirm with product diagram.

What components are included and why keyed-alike matters?

The kit includes one clockwise and one counterclockwise T-handle lock plus all fasteners and hardware needed to install both sides of a camper shell door. Keyed-alike means both locks use the same key, so you don’t manage different keys for left and right handles.

• Contents: 2 T-handles (CW & CCW), 2 lock bars, 1 cam plate spacer set, 4 mounting screws, 4 keys.
• Keyed-alike benefit: one key operates both locks—easier daily access and fewer spares needed.
• Extra keys included for backup or sharing with a partner.

What materials and durability features protect against outdoor exposure?

OTTOPO assembled the locks using corrosion-resistant metal finishes and robust internal components to handle wet and dusty environments typical of truck use. The finish and plated steel parts reduce rust and maintain smooth operation over time.

• Lock body: zinc alloy die-cast with matte black powder coating for weather resistance.
• Lock rod & bar: zinc-plated steel for strength and corrosion resistance.
• Precision cams and spacers included to ensure secure engagement and long-life wear.

How difficult is installation and what tools/steps are required?

Installation is straightforward for anyone comfortable with basic hand tools, but it requires verifying hole sizes first. If your existing openings are too small, you will need to enlarge the center hole to the specified diameter before mounting.

• Tools: drill with appropriate bits, screwdriver or socket set, measuring caliper recommended.
• Steps: confirm measurements, position handle, insert cam and lock bar, secure with screws, test lock operation.
• Note: center hole must exceed 5/8"; side holes must exceed 8.2 mm—some LEER caps may need minor enlargement.

Who this is for: This replacement kit is intended for truck owners with camper shells, toppers or caps using T311-style T-handles who need matched left/right locks or who prefer the convenience of keyed-alike hardware. It’s useful for do-it-yourself installers, fleet maintenance teams, and anyone upgrading worn or corroded camper shell locking hardware. If you own a select LEER, A.R.E., Century, Ranch, Jason, Astro or similar cap that accepts the larger T311 mounting pattern, this OTTOPO set offers a durable, ready-to-install replacement—just verify the hole dimensions shown in the product diagram first.
