F.H.Brundle supplies a comprehensive range of gate lock keeps and lock boxes for swing gates and sliding gates, available in aluminium, ERW, mild steel, galvanised steel, stainless steel, and polyamide. The range covers insert keeps, surface-mounted keeps, and full lock box profiles in 40 x 40 x 2mm and 40 x 40 x 2.5mm box section, with lengths up to 2100mm to suit standard gate frame dimensions. Products are compatible with the leading gate lock systems on the market, including the Locinox Forty Lock, Sixty Lock, Hybrid Lock, and Sliding Lock, as well as Gatemaster and Superlock configurations, making it straightforward to specify the correct keep or box alongside a new or replacement gate lock.

The range includes both insert keeps (fitted inside the gate frame RHS) and surface-mounted keeps for 40mm box section profiles, with options in stainless steel and polyamide to suit the lock type and application. Adjustable keeps are available for the Locinox New Generation lock range, accommodating installation tolerances on both swing and sliding gate installations. Whether you are specifying a gate lock keep for a domestic timber gate, a galvanised steel keep for a commercial swing gate, or a stainless steel lock box for a high-security or coastal application, the F.H.Brundle range provides the components to complete the installation.
