4040XP Tandem Door Closer - Extra Heavy Duty

The right choice of door control involves many factors, not least the ‘sail area’ - i.e. a combination of the door’s height x width. In general terms all Relcross heavy duty overhead door closers are capable of controlling conventional doors up to 136 kilos in weight although all doors must be free swinging with the correct choice of hinges and pivots being an important prerequisite.
