ERA multipoint door locks are some of the most popular on the market in the UK. Identifying an ERA multipoint door lock can be straightforward but there are some traps to watch out for.

The first trap is that ERA make locks for a huge number of different door and window companies, many of whom rebrand the locks. Often faceplates are stamped with the ERA logo, but they can also be stamped with brands such as Surelock, Saracen, Spartan, Duraflex, Supa, Westward or Cego, to name but a few.

A good indication as to whether the lock you are identifying is made by ERA is the holdback snib on the faceplate. This is often grey on deadbolt and hook bolt locks and blue on Vectis locks. However, some of the brands named above have changed the colour of the snib to black or green.

Its also worth noting that sometimes ERA locks are referred to Saracen. This harks back to the days when Laird made locks for the double glazing industry, before they were rebranded as ERA.

We'd always recommend removing the multipoint from the door to help identify it. This is especially important if you can't identify the brand from the faceplate or it has been rebranded.

ERA multipoint door lock gearboxes are very distinctive, with a square design and no corner cut outs. The overall length of the gearbox is 221mm and the width is 46mm.

ERA multipoint door lock gearboxes feature a 24mm high latch (with 2 distinctive screws in the latch), a 30mm high deadbolt and 61mm between them. Gearboxes are held on to the faceplate with 4 screws, which is unusual for a multipoint door lock. The first screw hole to the second measures 37mm, the second to the third measures 85mm and the third to the fourth screw measures 43mm.

When measuring the backset, allow 2-3mm for the faceplate, so a 35mm backset gearbox will measure 32mm when not fixed to the strip.

ERA Multipoint door lock deadbolts (referred to by ERA as linear bolts) feature an 18mm throw and are chamfered to pull the door against the frame.

Deadbolt locks are most frequently found fitted to timber and composite doors.
