The LCN 4040XP sets a new standard for reliability, longevity and value with a beefier design and extraordinary performance testing that goes far beyond industry requirements. We built the 4040XP from the inside out, combining tougher, bolder construction with proven LCN technology. The result is a closer that’s stronger, smarter and delivers remarkable value in a variety of applications. The 4040XP Tandem variant uses two mechanisms and is a Relcross Door Controls® custom solution.
The correct 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 a critical prerequisite. Where doors exceed the 136 kilo limit, a proven custom (Relcross) solution exists. Developed over many years the 4040XP.TANDEM Overhead Door Closer comprises two heavy duty cylinders - linked to produce considerable power without any loss of control - to suit doors to 272 kilos. An additional cylinder can be introduced for extra heavy doors in excess of 272 kilos - consult the sales office for further information.
