How does this lock fit my RV door?

The latch is designed for a standard 2.75" × 3.75" rectangular cutout and accommodates doors between 1.25" and 1.5" thick. It replaces many factory units directly, minimizing routing or filler work. Before buying, measure the cutout and door thickness to confirm compatibility.

• Door thickness range: 1.25"–1.5"
• Direct-fit design for common camper and trailer brands

What security and durability features are included?

Security centers on a tamper-resistant lock cylinder with unique key codes to reduce unauthorized duplication. A built-in deadbolt-style mechanism plus interior and exterior locking give reliable protection for stored gear. The housing blends zinc-alloy and reinforced plastic with UV- and corrosion-resistant finishes to withstand outdoor exposure.

• Unique-key cylinder supplied with four keys
• Durable zinc alloy lock body and reinforced plastic housing

How easy is installation and what comes in the box?

Installation is straightforward for anyone comfortable with basic hand tools: remove the old unit, orient the latch into the cutout, use the included screws and follow the step-by-step instructions. The kit supplies multiple screw lengths to suit different door materials and layers, plus spare parts to address common fit issues during replacement.

Will this lock perform well while traveling and in storage?

The materials and finish are chosen for long life in varied climates: the corrosion-resistant zinc alloy resists salt and moisture, while the UV-treated housing reduces sun damage. Smooth internal mechanics minimize sticking from vibration, and the tamper-resistant cylinder helps protect belongings during stops or in storage facilities.

• Corrosion-resistant metal components for coastal or rainy climates
• UV-resistant surface to limit sun degradation
