Interior Door Lever Lock Set (Aluminum Alloy, Quiet Latch)
Key points
- Solid lever with an internal steel-ball bearing keeps the handle quiet and firm
- Twin-roller latch closes with a damped click instead of a rattle
- Aluminum alloy body with a 72-hour salt spray rating resists rust indoors
- 45 mm backset and the small-50 pattern suit most interior door preparations
- Hotel and apartment refurbishments can replace worn handles across many rooms from one part number, keeping the existing keys and cylinders in service
- Builders merchants can hold a single part number for an apartment block, so a replacement is pulled from the shelf instead of being matched against a discontinued model

Product detail
Interior door lever lock set built for bedrooms, offices and steel-wood doors where the door is opened and closed all day and noise carries. The body is cast in aluminum alloy and treated against rust and corrosion, passing a 72-hour salt spray test, while the lever is solid rather than hollow so it keeps its shape under daily use. A steel-ball bearing sits inside the handle and the latch carries twin rollers, so the door closes with a damped click instead of a rattle. The latch uses a double-bolt layout, a sprung latch plus a separate deadbolt, which gives basic security without a bulky mortise body. Fitting follows the common small-50 pattern with a 45 mm backset, and the set can be supplied with 304 stainless hinges, a door stop and keys. Gunmetal gold and bright chrome finishes cover both traditional and modern interiors. Landlords and housing providers can fit the lever to doors used by older residents, since the handle is easier to work than a round knob when grip is limited. Housebuilders and joinery suppliers fit this where a domestic door needs a lever that closes quietly; the aluminium body keeps the cost sensible for volume work while the latch is damped enough not to rattle in a draught.
