Product: Lock-body installation tool set What’s included Two lock-body screw wrenches: one long-handle and one short-handle wrench to cover different door and lock-body installation needs. Key benefits — why you need it Precise installation: Etched measurement scales allow exact adjustments during fitting and reduce common alignment or sizing errors. Better access and control: Long and short handles give reach into tight cavities or close-to-hinge areas and provide the leverage needed for secure fastening. Built to last: Solid stainless steel construction resists wear and corrosion so the tool keeps working and looking good over time. Comfortable, efficient use: Ergonomically shaped handles deliver a secure grip and reduce hand fatigue during repeated or extended installations. Performance and compatibility Function: Designed specifically for installing and adjusting lock bodies and associated screw fastenings; the set supports accurate alignment and consistent torque application. Material: High-grade stainless steel for strength, durability, and corrosion resistance. Size/fit: The two-handle options cover common installation situations where either reach or compact access is required; etched scales support exact positioning and repeatable results. Practical use scenarios Installing a new deadbolt or mortise lock in a residential door: use the long-handle wrench for reach into deeper cavities and the etched scale to set precise lock-body depth. Replacing or adjusting an existing lock on a commercial or apartment door: the short-handle wrench provides controlled access in tight trim or frame spaces while the ergonomic grip reduces installer fatigue. Professional locksmith or maintenance work: durable stainless construction and clear scales speed repeated installations and minimize rework. How it solves common problems Reduces measurement mistakes with permanent etched scales. Reaches awkward places and provides necessary leverage with two handle lengths. Maintains functionality across jobs and environments thanks to corrosion-resistant stainless steel. Lowers operator strain and improves steady handling through ergonomic grips. Usage notes Choose the long or short wrench depending on space and reach. Use the etched markings to verify depth and alignment before final fastening. Clean and store dry to preserve finish and scale legibility. A reliable, no-nonsense tool set for accurate, durable lock-body installation and adjustment.
