ERA Latch 3 Hooks 4 Rollers Split Spindle Multipoint Door Lock

This ERA Hookbolt multipoint door lock features 4 Rollers, 3 Hooks & 1 Latch.

ERA locks may also be stamped Homesafe, Surelock, Saracen, Spartan, Duraflex, Supa, Westward or Cego.

Originally designed to replace GU, Lockmaster and Winkhaus locks without the need for new routing positions these locks are available in 2 options.

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.

All ERA hookbolt multipoint locks feature a split spindle mechanism which makes replacements easier as you only need to be concerned with one locking function (excluding the auto locking SureFire locks).

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 the backset plus 18mm.

Available in 30mm, 35mm or 45mm backsets, all ERA gearboxes have the same dimensions. They can feature a classic deadbolt with either a standard euro cut out, Invincible cylinder cut out or Vectis 5 lever mechanism. They can feature either a deadbolt or hook bolt (which throws upward). Look out for the British Standard Fortress invincible gearbox which features hardened drill plates.

With the exception of the British Standard Fortress lock, all ERA gearboxes can be interchanged, so if your client needs a hook lock, instead of a deadbolt or a Vectis locking multipoint door lock, contact us and we'll build the lock to order.

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.

The first is a standard hook which features one of the smallest hook cases on the market. They are really useful when replacing an obsolete lock and the routing is tight.

The second type of hook is a security steel hook, which features a much larger hook case. Upgrading from a small hook to large hook lock can require a little work to the door, to allow the larger hook cases to fit.

All ERA hooks a bi directional, with the top hook throwing upwards and bottom hook throwing downward, for higher security.

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.
