The RYOBI 89041038052 is an OEM replacement knob for the miter gauge assembly on RYOBI and RIDGID stationary power tools. The miter gauge knob secures the miter gauge angle setting, allowing the operator to lock the gauge in position before making a cut. This is a factory-original part, not an aftermarket substitute. Woodworkers and tool repair technicians install this component when the original knob is lost, cracked, or stripped. Because it is an OEM part, it is manufactured to the same specifications as the knob installed at the factory.
This knob is intended for use with miter gauge assemblies on RYOBI and RIDGID table saws or similar stationary cutting equipment that uses this gauge style. It is a direct OEM fitment part, making it suitable for service technicians performing warranty or out-of-warranty repairs on applicable units. Consult the tool model's parts diagram to confirm this knob matches the miter gauge subassembly on the specific unit being serviced.
Designed as an OEM-style replacement for RYOBI and RIDGID stationary power tools equipped with a compatible miter gauge assembly. Verify fitment against the specific model's parts diagram before ordering.
Installation should be performed by a qualified technician or experienced operator familiar with stationary power tool service. Disconnect the tool from its power source completely before beginning any parts replacement. Hand-tighten the knob onto the miter gauge rod or stud; do not use power tools to install a plastic or resin knob, as overtightening can cause cracking or thread damage. Refer to the tool's service manual for the correct miter gauge assembly procedure.
