Espag type window mechanisms
These are an older style of UPVC window lock but still incredibly popular today. While a few models have been made obsolete over time, we can usually offer a close match that’ll work with just a touch of adjustment.
Getting the right size is key: You’ll need to know the backset, overall length, and whether your lock is inline or offset. Click here to view our step-by-step measuring guide – it’ll walk you through exactly what to measure so you get it right first time.
Matching things up properly makes fitting easier and ensures the new lock lines up clean with your window handle. No bodging required. We stock mechanisms from top brands like Maco, Avocet, Coldseal, and Trojan – ready to drop in or tweak as needed.
Still not sure? Give us a bell and we’ll help you sort it before you’ve even opened your toolbox.
