Era Surelock / Saracen 35mm
Faceplate: 16mm / 20mm
Single spindle with a split follower so you can use a solid or a split spindle. In early versions of this gearbox the deadbolt was thinner so you may have to open up the bolt gap in the faceplate with a metal file, this will allow the thicker deadbolt of the new gearbox to pass through. This gearbox fits 16mm & 20mm faceplates.
The Era Vectis, Era Hook and Era Deadbolt cases are interchangeable as long as the backset is the same. For example, you can replace a faulty Era Vectis 35mm with an Era Saracen 35mm. A deadbolt case will work with hook keeps/strike plates but hooks won’t work with deadbolt keeps/strike plates unless you modify them.
Failed gearboxes can most often be opened with the A’ Jam Rescue Tool.
To fit the new case you must first remove the fixing screws from the faceplate and remove connector rods. With the new case, place the faceplate over the latch and connect the connect rods. These sit over 2 little pegs at either end of the case. Once fitted correctly, use the 4 screws to secure the faceplate. You may need to turn the latch the opposite way depending on which way the door closes. To do this, loosen the 2 screws in the latch, turn the latch 180 degrees and then tighten the screws back into position.
To change the handing (when using a split spindle), loosen the 2 latch screws and remove the latch. With a small flat screwdriver insert into the latch carrier and rotate 180 degrees, then replace latch and screws.
Current price range for this part is roughly £18 - £40.
