The Multiquip 503015 Adjustable Handle Knob is a genuine OEM component designed for the AR13 and RW-series ride-on rollers, including AR13D, AR13H, AR13HA/HAR, AR13HC, RW1404, RW1404MR, and RW1504HF models. As a direct OEM replacement, part 503015 matches the original specification for a straightforward, hassle-free installation on your Multiquip roller. Sourced directly through authorized distribution channels, this knob delivers the same quality and dimensional accuracy as the part that left the factory. If your current handle knob is stripped, cracked, or simply worn out, replacing it with the correct OEM part ensures proper handle adjustment function is fully restored.
Key Features
- Genuine OEM Construction — Molded and threaded to the same dimensional spec as the original, ensuring the adjustment mechanism engages and locks exactly as intended.
- Drop-In Handle Installation — Threads directly onto the existing handle adjustment post with no reworking of surrounding hardware required.
- Broad Ride-On Roller Coverage — Confirmed fitment across AR13D, AR13H, AR13HA/HAR, AR13HC, RW1404, RW1404MR, and RW1504HF roller models.
- Restored Operator Control — A worn or stripped knob prevents secure handle positioning; replacing it brings full, positive handle adjustment back to the operator.
- Correct Part Number Confidence — Multiquip 503015 is the exact OEM reference for this knob, eliminating guesswork when ordering for your roller fleet.
The adjustable handle knob on a ride-on roller allows the operator to set and lock the steering handle or control handle at the preferred working position. When this knob wears, strips, or breaks, the handle can no longer be secured in place, making precise control of the roller difficult and creating operator fatigue over long compaction runs. Replacing a damaged knob promptly with the correct OEM part restores firm, reliable handle positioning so the machine can be operated safely and efficiently.
