This gearbox accepts the ERA Invincible shaped cylinders and a converter piece to allow a euro to be used. The 35mm backset features a hook, rather than a deadbolt.
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 a 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.
We stock a range of associated products for ERA Hookbolt gearboxes, including multipoint door locks, keeps, spindles, handles and accessories.
