Product Information

This part is discontinued and is no longer available.

However, part: G13764 is a potential alternative. This replacement Ferro lock is 4 roller version only. The keeps will need to be adjusted.

A unique latch only Ferco lock that features an additional hook as well as two mushrooms and 2 rollers.

The Tripact lock features a deadbolt, in contrast to the standard Ferco locks. Ferco locks are part of the GU group of companies. They are fairly unique as they feature 70mm centres (PZ) and can therefore be easily identified.

The Tripact Ferco UPVC door lock features a latch and deadbolt in the central gearbox, with 2 or 4 rollers or a pair of small flip or tongue hooks. While they are high quality, they offer low security by modern standards and new doors are no longer manufactured with these locks. Nevertheless, they have been fitted to thousands of doors over the years and there is a substantial replacement requirement.

Often fitted to timber doors, the trip act flip hooks were designed to be shallow, to require as little door preparation as possible.

In fact the original Tripact locks were also latch only, but a deadbolt was added to improve security. The original locks had a 20mm faceplate with a T shaped rail that ran behind it. They were only available with a 40mm backset. New versions feature a deadbolt and a slightly smaller faceplate. The hooks line up but a new deadbolt keep will be required if you are replacing a very early lock.

The spindle is solid, with a standard lift lever function. However, the spindle is only 7mm, compared with standard locks at 8mm. 70mm PZ handles will be supplied with a 7mm spindle to suit these locks, but its important to be aware of this difference.

Gearboxes measure 212mm high x backset + 15mm wide.

Rollers are used for compression, to pull the door against the frame, to help prevent dust or water ingress. They do little for security, but they also have the added benefit of helping to prevent the door from becoming warped as it is supported across its full height. This is dependent on the rollers being engaged into their keeps.

Rollers are normally adjustable by +/- 1mm to help achieve optimum weather sealing.
