This is a plastic white / black seat rail guide. This fits on folding wheelchairs that have detachable armrests. These fit inside the rear of the seat frame pipe which is a 7/8tube. This helps the chair fold and unfold smoothly and keeps the seat inline with the back when opened. This front U-shaped seat rail guide supports and connects the seat frame tubes to the back frame tubes. This black plastic part keeps the chair lightweight as it negates the need for heavy welded steel framing.
