The Dzina Sliding Tower Door Bolt is an ideal security solution for homeowners and DIY enthusiasts looking to reinforce gates, shed doors, and garage entrances. Engineered from heavy-duty gauge steel, this bolt offers robust protection against forced entry while maintaining a smooth operation for daily use; however, its substantial 250mm length requires a flat, sturdy mounting surface to ensure the bolt aligns correctly with the keeper.

Yes, the heavy-duty steel construction makes it suitable for outdoor gates, sheds, and garages.
You will need a drill with bits for pilot holes, a screwdriver (Phillips head), and a pencil for marking alignment.
This specific guide covers the 250mm x 48mm model; please check your specific product packaging for size variations.
Yes, the product comes with the necessary screws for installation.
While made of durable steel, applying a light coat of exterior-grade lubricant periodically will help protect the finish and moving parts.
Check for debris in the sliding track and ensure the mounting screws are not overtightened, which can warp the steel casing.
Loosen the mounting screws slightly to shift the bolt base into alignment, then retighten once the bolt slides smoothly into the receiver.
To install, ensure the door and frame are flush. Position the bolt on the active door panel and mark the screw holes with a pencil. It is highly recommended to pre-drill pilot holes to prevent the wood from splitting, especially when mounting into dense timber. Align the keeper on the frame so that the bolt slides into the center of the aperture without binding. For maintenance, keep the sliding channel free of debris and apply a light silicone-based lubricant annually to ensure the mechanism remains fluid and rust-resistant, particularly for gates exposed to direct rain or coastal air.
