MEASURING YOUR HANDLE Screw Hole Fixing Centres: Most espag handles are made to industry standards with 43mm screw hole centres, therefore it really doesn’t matter if you choose a style that’s different to your existing handle, as long as the handle centres measure 43mm these handles will fit.Handing: These handles are of the inline type (Non-handed), therefore they will replace both left and right hand handles.Spindle Length: Remove the two screws fixing the handle to the window and measure from the base of the handle to the tip of the spindle.Spindle width: Although almost all espag spindle widths measure 7mm square, its worth checking before ordering as some unusual 8mm variations have been known, although these are mostly on timber windows.
