Squire Die-Cast Steel Combination Locking Bolt 50mm (27477)

Sorry for the delay in replying to you. The bolt extends over 15 mm. The product also comes with a flat steel keep that will cut down the 10 mm gap if you fit it to the face of the hole. You may also be able to overhang the bolt slightly to reduce the gap even more.

Hi please try the following steps 1. Set the wheels to the combination you have tried setting it to. 2. Push and hold the button at the bottom. 3. While at the same time, use the pin provided and starting from the bottom wheel (closest to the button) and wiggle the wheels slightly left to right. 4. If the wheels stick in place, leave it there and move on to the next wheel above. 5. You will find it will spring open as soon as you have positioned it correctly. Once you have it in the open position, reset the wheels which are offline. If this doesn't work you will need to return the padlock to us, we will examine it under our 10-year guarantee.
