Gearboxes for UPVC Windows
UPVC window gearboxes are the central part of a 3-piece lock and can usually be replaced on their own. Rods or shootbolts rarely need changing, but we stock them if required. The lock is secured with retaining screws and the handle bolts, which must be removed to take it out.
Full Length Window Locks
Older but still popular. Some espag locks are obsolete, though alternatives are available with minor adjustment. Check backset, overall length, and whether it’s offset or inline. See the measuring guide.
Keeps & Screws
All the extras to fit your espag lock or gearbox. Missing screws/keeps can slow the job down. If you’re replacing an obsolete lock, you may need extra keeps/screws to make the alternative fit. Need help? Call 01204 652211.
