PTM Edge KNB - 050 Replacement Knob - Black

The PTM Edge KNB-050 replacement knob in black is a direct-fit component engineered for users running aftermarket mirror systems who need a reliable, durable control interface. This knob serves as the primary manual adjustment mechanism for popular VR-140 Pro and PXR mirror assemblies, making it an essential replacement part for mechanics, off-road enthusiasts, and vehicle builders who demand precision adjustability in their mirror positioning. Whether you're fine-tuning sightlines on a lifted truck or replacing worn controls on a heavily modified platform, this purpose-designed knob restores full functionality to your mirror system.

Constructed from ABS polymer with a 3/8-inch collar diameter and threaded brass connecting insert, the KNB-050 delivers both durability and corrosion resistance in demanding environments. The ABS material resists UV degradation and temperature cycling common in automotive applications, while the brass insert provides consistent thread engagement and prevents stripping over thousands of adjustment cycles. The midnight black finish matches OEM mirror housings while remaining virtually invisible against darker trim, maintaining the clean aesthetic of professional mirror installations without drawing attention to auxiliary components.

This replacement knob is ideal for owners of vehicles equipped with VR-140 Pro or PXR mirror systems who experience worn, cracked, or missing control knobs. Installation is straightforward—the threaded brass insert screws directly into existing mirror mounts without requiring additional modifications or adapters. The unit weighs approximately 1 pound and ships as a single component, making it easy to keep as a spare in your vehicle maintenance kit or carry-on for extended expeditions where reliable mirror adjustment is non-negotiable.
