cylinder lock

These locks are made from a range of materials including zinc alloy, laminated steel, hardened steel, plain steel, aluminum (often vinyl-covered), and other general metal constructions.

Example specifications include an adjustable outer-handle hole spacing of 7-11/16" to 8-13/16" (195–224 mm). One listing gives overall dimensions as 2.9" H × 1.8" W × 11.5" D — other listings may show different product dimensions.

Features highlighted for outdoor and industrial use include corrosion- and cut-resistant components (stainless or hardened steel shackles), vinyl-covered or weather-resistant bodies, non-conductive bodies for safety lockout applications, and included weatherproof lockout tags.

Warranty periods vary by product; examples shown include a 3-month limited warranty, a 1-year limited warranty, and lifetime limited warranty options.

The listings show pin-tumbler cylinders (commonly four-pin) and double-locking (dual-locking) lever mechanisms across the padlocks and cylinder sets.

Lock-core kits are described as quick to install — tool-free in many listings and taking about five minutes. Kits include multiple cores with matching keys and a control key.
