The 282 Aluminum Door Piston Latch is a piece of nickel-plated steel, intended to be placed on the inside of the module to hold the aluminum door opening piston. It provides the necessary firmness to locate the piston so that does not move or run anywhere after installation. Each package contains a total of 100 units for wood or aluminum doors PLUS 7-8-10. Due to their size, it is recommended to keep parts out of the reach of small children and in isolated storage to avoid their loss.
