This kit is a replacement for the Roto GR400 Lozenge shaped window espag (see picture) that is not made anymore.



The kit comes with a Window locking strip and new keeps to fix on to the window frame(screws included).

To use this kit you have to remove the old keeps of the frame and renew them with the keeps supplied. There may be some resiting of the holes and this is easily done using the easy drill screws provided with the Kit.


Parts included

  • 1 x400mm offset Window Lock
  • 2 x Universal window keeps
  • 10 x 25mm Self drilling super screws

    Obsolete window hinges - they fit!

    Posted by Kate on Jan 13, 2022

    Delighted to find these online so we could fix our window hinges without replacing the entire unit! The window is now obsolete but they were the right code, we did have to make some minor alterations and buff the fitting but it worked and now open & close perfectly.
