What is a polished chrome espagnolette surface bolt?

An espagnolette surface bolt is a surface-mounted bolt with a vertical rod that locks into the frame at the top and bottom. The polished chrome finish provides a sleek, modern look while improving door or window security.

Are espagnolette bolts suitable for French doors?

Yes. They’re commonly used to secure the inactive door leaf by engaging into the head and threshold, adding stability and stronger security compared with basic flush bolts.

Can I fit these bolts on tall casement windows?

In many cases, yes. Espagnolette surface bolts work well on taller openings where top-and-bottom engagement improves hold and reduces movement, provided the bolt length and fixing points suit your frame.

Should I choose a locking or non-locking espagnolette bolt?

Locking bolts are best for external doors or areas where additional protection is needed. Non-locking options are often used internally or where a key lock is not required.

What should I check before buying an espagnolette surface bolt?

Check the door or window height, confirm the opening direction, and ensure there’s suitable frame depth for the top and bottom keeps. If matching existing hardware, confirm the polished chrome finish suits your other fittings.
