Latches & Catches

About latches & catches

Latches and catches secure panels, doors, and access points, providing both closure and, in some variants, compression or vibration resistance. Common types include draw latches, which pull components together with a toggle action; compression latches, designed to apply a sealing force and dampen vibration; slam latches, which engage automatically upon closure; cam latches, which rotate a cam to secure a panel; and magnetic catches, offering non-mechanical retention. Selection parameters typically include grip range or panel thickness for cam and compression latches, tensile or shear strength ratings for draw and slam latches, and holding force for magnetic catches. Dimensional considerations such as overall length, width, and mounting hole patterns (e.g., 4-hole, 2-hole, single-hole) are critical. Materials often include zinc-plated steel for general industrial use, stainless steel (304 or 316) for corrosion resistance, and engineering plastics like nylon or ABS for lightweight or non-conductive applications. Finishes such as powder coating, chrome plating, or electropolishing enhance durability and aesthetics.
