FRICTION STAYS For repairs always use a 4.8mm domed head screw, either self- tapping if going into reinforcing or fast thread if going into PVCu only. We would always recommend stainless steel fixings for friction stays, and keep at least two sizes handy( 20mm and 30mm or thereabouts) to ensure the screw is the correct length. |

more regularly for environments where the furniture is exposed to dirt, water or salt.
WINDOW MAINTAINANCE Windows require very little attention, but to maximise longevity here are some quick and easy tips: At least twice a year open the window fully and clean out any debris, cobwebs or insects from the sash and frame particularly around any hardware parts. PVCu frames can generally be cleaned with warm mildly soapy water and a non-abrasive cloth.

LUBRICATION OF HARDWARE The hinge mechanisms and locking mechanisms would benefit from lubrication at least once and preferably twice a year. Lubricate with a silicon spray around all parts with metal to metal contact. This means the moving locking parts of the window lock and all the riveted parts of the door hinge.
ADJUSTMENT OF HARDWARE If the window operates easily and without undue resistance then lubrication is enough, but if the locking mechanism becomes stiff,
|
then in most cases it is possible to adjust the locking cams on the lock. Most locks will have an Allen Key adjustment in the centre of the locking point. They should be preset to a neutral position when the window is made but this may not be the case once installed. The easiest way to adjust a stiff window is to adjust each locking point so that the locking point is moved as far towards the opening side as possible. This should give the minimum amount of compression and make the window as easy to lock as possible. If it is too loose then turn the |
locking points back towards the closing side.
REPLACEMENT OF HARDWARE The only component on a window that is easily replaced by a DIY-er is the espagnolette handle. Buy an Easyfit Repair Espag pack or Versa Repair Handle and these should come with everything needed to replace the handles including screws and instructions. It is not recommended that window hinges or locking systems are replaced by anyone other than a tradesman – even replacing like for like might be a mistake if the
|
hardware is wrong for the window in the first place. It is all too easy to ruin a perfectly serviceable window if not properly skilled.
REPAIRING SCREWS Choosing the right fixings for new windows and doors is reasonably straightforward, but using the right screw for repairs can be more complicated and much more likely to be problematic. As one of the leading suppliers of Repair Hardware through our Easyfit range Winlock has vast experience in this area and can help you chose the right repair fixing:

HARDWARE INTO REINFORCING If making a new hole, then use a 3.9mm countersunk self-tapping screw of the correct length( 30mm will cover many applications but not all). If the screw is to go into an existing hole then a 4.8mm countersunk repair screw is more appropriate( these typically come in 25 and 38mm so have both handy).
HARDWARE INTO PVCU If making a new hole then a 4.3mm countersunk fast thread screw with a gimlet point should be used, 30mm length will cover most but not all applications. If the fixing is into an existing hole then a 4.8mm countersunk repair screw should be used again in either 25mm or 38mm length.
