Abstract: Roll-in cots having wheel alignment mechanisms. According to one embodiment, a roll-in cot includes a support frame, a pair of legs pivotably and slidably coupled to the support frame, and a pair of hinge members that are pivotably coupled to the support frame and to one of the legs. The roll-in cot also includes a wheel linkage pivotably coupled to the pair of legs and a wheel alignment mechanism.

Abstract: A sectional overhead door is customized by including overlay members selectively mounted to the panels. The front face of the panels may have a design stamped or embossed therein to simulate the vertical slats of a wooden carriage house door. The door panels and the resulting door is customized with the addition of overlay members simulating the transverse or diagonal wood slats on traditional carriage house doors. The overlay members are selectively mounted to the front skin of the door panels at a variety of locations and orientations to mate with the design on the front skin of the panels.
