The PowrLiner 90063 is a frame cap component designed to fit specific frame tubing on select PowrLiner striping equipment. This cap serves as a protective seal for open frame ends, preventing the intrusion of dirt, debris, moisture, and other contaminants that can accumulate within the frame structure during normal operation. Over time, exposure to job site conditions can cause original frame caps to become brittle, crack, or become dislodged, leaving frame tubing exposed to environmental elements that may contribute to corrosion or internal debris buildup.
The frame structure on striping equipment is subject to constant exposure to paint overspray, road debris, moisture from washing operations, and temperature fluctuations that can affect plastic components. When frame caps are missing or damaged, open tubing ends provide an entry point for contaminants that can settle inside the frame, adding unnecessary weight and potentially trapping moisture against metal surfaces. Replacing deteriorated or lost frame caps helps maintain the original protective envelope of the equipment frame and supports long-term structural integrity.
This frame cap is manufactured to match the original equipment specifications for frame tubing dimensions and material composition. The cap is designed to fit securely into the frame opening, providing a friction-fit seal that remains in place during normal equipment operation and transport. Installation requires no special tools and involves simply pressing the cap into the open frame end until it seats fully against the tubing edge. Before installation, the frame end should be cleaned of any debris or old adhesive residue to ensure proper fit and retention.
Compatibility verification is essential before ordering this component, as frame tubing dimensions vary across different PowrLiner model lines and series. The 90063 frame cap is designed for specific frame configurations and is not a universal component across all PowrLiner equipment. Service technicians should confirm fitment by referencing the original parts diagram for the specific model being serviced or by measuring the frame tubing opening to ensure proper sizing. When installed on compatible equipment, this frame cap restores the original protective sealing function and contributes to the overall preservation of the equipment frame structure.
PowrLiner part 90063 is designed for select PowrLiner striping equipment. Careful attention to compatibility is required, as this frame cap does not fit several PowrLiner model lines. Always confirm fitment using the correct parts diagram for your exact model and revision before ordering.
Refer to original equipment parts diagram for specific model compatibility. Frame cap fitment is determined by frame tubing dimensions specific to certain production runs and model configurations.

When servicing frame components, several related parts are commonly inspected to ensure complete protection of the equipment structure.
Inspect all frame end caps on the equipment simultaneously, as multiple caps often experience similar wear and UV exposure.
Inspect frame ends for signs of corrosion or debris accumulation when caps are removed. Clean thoroughly before installing new caps.
Inspect related frame-mounted rubber components that may show similar age-related degradation.
