Wood patio door rollers are mechanical components that support and guide sliding doors along their tracks. These drive-in style assemblies install into a rectangular mortise cut into the bottom edge of wood sliding doors, typically Pella models. Each unit features a heavy-duty 1-1/2 in. steel ball bearing wheel with a concave tread surface for smooth rolling and reduced lateral wobble. The housing measures 2-3/4 in. in length and 11/16 in. in width, constructed to withstand repeated use and seasonal expansion. A rear-mounted cross-head adjustment screw enables precise height calibration without removing the door. Installation requires the screw head to face the door's stile or vertical edge for proper access. These rollers are not interchangeable between old and new Pella designs-the flanged version will drag on older track systems. Replacing both rollers simultaneously ensures even weight distribution and consistent door alignment. They function exclusively with wood-framed sliding patio doors and require no adhesive, welding, or specialized tools beyond basic hand screwdrivers.
