Ever tried to install an ADI SL5 Slimline Locking Bolt and realized the door gap is more like a canyon? Or maybe you're tired of eyeballing the drill holes and hoping for the best? We've been there, and we've fixed it.

Dual-Purpose Genius: Template & Packer

This isn't just a bit of plastic. It’s a precision-engineered ADI SL5 drill template that ensures your mounting holes are spot-on every single time. Once the holes are drilled, don't throw it away—it doubles as a 6mm spacer/packer to bring your lock into perfect alignment.

• Precision Fit: Specifically designed for the ADI SL5 Slimline series.
• Durable Material: Tough 3D printed construction PETG that stands up to the job site.
• Saves Time: No more "measure twice, swear once." Just line it up and drill.

Why you need this

Look, you could spend twenty minutes trying to find a scrap bit of acrylic to shim that lock, or you could use this and be at the pub by 4:00. It’s a drill guide and a packer in one. It’s like a Swiss Army knife, but actually useful for locksmiths. Don't be the bloke struggling with a lopsided bolt—get it right the first time.
