Patio Door Security Bar — Heavy Duty | Steel Lock Bar for French & Patio Doors — UK Made

Patio doors and French doors are one of the easiest entry points for burglars — the Warrior Weld Patio Door Security Bar (Heavy Duty) stops them in their tracks. This is our top-spec bar, built to a heavier construction for maximum resistance, and fabricated from steel right here in the UK. It fits firmly across the door handles, preventing the doors from being forced open even if the lock is bypassed.

Quick to fit and remove, it works on most standard French doors, sliding patio doors, and double doors. No drilling or permanent fixing required — simply place across the handles when you need it.

Frequently asked questions

Will it fit my doors?
Our security bar fits most standard French and patio door handle configurations. The bar is adjustable in length to accommodate different door widths. If you're unsure, contact us with your door handle measurements.

Do I need to drill or permanently fix anything?
No — the bar simply sits across the door handles on the inside. No drilling, no permanent installation, and no damage to your door or frame.

Can it be used on sliding patio doors?
Yes — it works on sliding doors as well as French doors and standard double doors.

Is it easy to fit and remove quickly?
Yes — it can be placed and removed in seconds, making it practical for daily use rather than just overnight.

Does it work if someone breaks the glass?
The bar prevents the doors from being pushed open via the handles. If a burglar breaks the glass entirely, they could reach in and remove the bar — so this is best used as part of a layered security approach alongside window security.

What's the difference between this and the Standard version?
This Heavy Duty bar uses a more robust construction for extra strength. If you want a lighter-duty option at a lower price, see our Standard Patio Door Security Bar.
