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 .
