Description
A black motorised drop bolt that locks the fixed leaf of an automatic swing gate for you. Wired to the warning light or the gate controller, it lifts its 20mm bolt before the gate opens and drops it again when the gate has shut. The black powder-coated aluminium housing is vandal resistant, an obstacle sensor stops the bolt if it meets more than 18kg, and a key releases it by hand in an emergency. Fail close: without power the bolt stays down. The price is for one drop bolt.
Why choose this drop bolt
Hands-free. The bolt lifts and drops with the gate's own cycle, so the fixed leaf is always locked.
Safe. Obstacle detection stops it at 18kg of resistance, and a key releases it if the power is off.
Built to last outside. A vandal-resistant powder-coated aluminium housing with a 5m cable included.
Where it is used
Automated double swing gates on homes, estates, business parks and car parks with stiles of 40mm or more.

Fitting
Fix the housing upright to the fixed leaf's stile through three 15mm holes, at least 20mm above the ground. Set a ground stop under the bolt. Wire the bolt to the warning light output (at least 3 seconds pre-warning) or the gate controller and to its matching power supply unit, then run the gate through several cycles to confirm the bolt lifts before the gate opens. Wiring should be done by a competent installer.
Frequently asked questions
Is the price for one drop bolt?
Yes, one drop bolt.
Is a power supply included?
No. It needs its matching power supply unit, sold separately. Call us and we will confirm the right one for your gate.
What happens in a power cut?
It is fail close, so the bolt stays down. Use the key to release it by hand.
