Description

 AVOCET / WMS OFFSET WINDOW ESPAG LOCK DESCRIPTION

The espag is the window locking mechanism, which is operated by the window handle. Offset window espag locks are commonly found on old uPVC windows. The gear box (the section the window handle connects to) is offset to one side. This was to accommodate the uPVC window profiles that were being manufactured at the time. The available space inside the profile for a window espag lock was very small. Modern uPVC window profiles are bigger and space is not an issue as it once was. Nearly all modern uPVC windows use inline window espag locks. As a result of the switch to using inline window espag locks, offset window espag locks now are a thing of the past. Many window hardware manufacturers have stopped making offset window espag locks.

Note: Please check sizes carefully against the sizes you  require

AVOCET / WMS OFFSET LOCK SIZE GUIDE

Unlike some other window espag locks, the avocet window espag lock has no size markings on the faceplate. You will have to check the overall length of the window lock.

You will also have to check the backset. Get a measuring tape and measure from the edge of the faceplate to the centre of the handle. There are two sizes available – 22mm & 25mm. Alternatively, you can remove the lock from the window. On Avocet offset window espag locks the backset size will be stamped on to the gearbox of the window lock.

We have the following lengths available in 22mm backset:

  • 600mm – 2 roller cams
  • 800mm – 2 roller cams

We have the following lengths available in 25mm backset:

  • 250mm – 2 roller cams
  • 400mm – 2 roller cams
  • 600mm – 2 roller cams
  • 800mm – 2 roller cams
  • 1000mm – 3 roller cams

The last size to check is the width of the lock. The width of the Avocet offset window espag locks we stock are 16mm wide. This is an important size to check as there are slimline versions that measure 14mm wide. These slimline versions are not being manufactured anymore.

Please contact us if you are unsure of the size window lock you require.
