Spring-Loaded Drop Bolt 300mm with Padlock Tab and Keeper, 12mm Bolt

A spring-loaded drop bolt that snaps down and holds a gate or door shut by itself. The 305mm yellow zinc-plated plate screws, bolts or welds upright to the gate. A coil spring pushes the 12mm bolt down 49mm into the keeper supplied or a hole in the ground, so the bolt stays down even when the gate is shaken. Lift the handle and drop it into the notch at the top of the plate to hold the bolt up. A tab with a 10mm hole takes a padlock to lock the bolt down. The price is for one drop bolt with its keeper, minimum order 5.

Why choose this drop bolt

Spring-loaded. The spring drives the bolt down into its keeper, so it cannot bounce or vibrate out when the gate is rattled or the wind catches it.

Holds up, locks down. Rest the handle in the top notch to keep the bolt raised while the gate is open. Put a padlock through the tab to lock it down.

Screw, bolt or weld. Four fixing holes suit timber gates and doors; on steel gates bolt it through or weld the plate.

Longest 300mm size. The 305mm plate spreads its four fixings along tall gate stiles and field gate heads, and the longest spring gives the strongest drop.

Where it is used

Garden and side gates, the fixed leaf of double gates, field gates, stable and shed doors, garage doors and bin store doors.

Specifications

Which bolt do you need?

Fitting

Close the gate and hold the drop bolt upright against it near the bottom, with the bottom of the plate 15 to 25mm above the ground. Mark and fix it with four screws (timber) or bolts (steel), or weld the plate to a steel stile. Let the bolt drop and mark where it lands. Either screw the keeper to a sleeper, step or post at that point, or drill a 14 to 16mm hole about 50mm deep in concrete or paving. Check the bolt drops cleanly, then fit a second keeper or hole where the gate stands open if you want to hold it open too.

Care

Put a drop of oil on the spring and guides twice a year, and keep the hole or keeper clear of grit so the bolt drops fully.
