An assembly has a frame that defines at least one opening and a subsystem that is movable relative to the frame. At least one slide connects the subsystem to the frame such that the weight of the subsystem transmits a force to the slide. The slide includes at least one projection that extends through the at least one opening in the frame. At least one urging member biases the projection to at least partially counter the force transmitted to the slide by the weight of the subsystem. At least one docketing pin slides into at least one docking hole with minimal vertical load on the docking hole.
