Capture plate that slips directly over a Lippert 1621 HD king pin box, giving your PullRite SuperGlide hitch the connection it needs to slide and pivot smoothly through turns. A required component for SuperGlide operation, built for quick installation and removal.
Every PullRite SuperGlide fifth wheel hitch requires a capture plate to function. The 331711 QuickConnect Capture Plate is built specifically for Lippert 1621 HD (heavy duty) king pin boxes, 12-3/4" wide, giving you a direct, purpose-fit connection rather than a universal plate that needs extra adjustment.
Once installed on your trailer's king pin box, the plate's wedge isolates the king pin from turning freely in the fifth wheel plate. That isolation is what activates the SuperGlide's cam assembly, allowing the hitch to slide back along its rails during turns and keep your trailer from contacting the truck's cab.
Purpose-built for 12-3/4" wide heavy-duty king pin boxes
Required to let the hitch slide and pivot through turns
Slips over the king pin, secured with set screws
SAE J2638 tested and rated to meet or exceed industry standards
PullRite's official listing identifies this capture plate as fitting the Lippert 1621 HD (heavy duty) king pin box — "Slim-Glide" doesn't appear in PullRite or Lippert's product naming for this part. Confirm your pin box is a Lippert 1621 HD model, 12-3/4" wide, before ordering.
This capture plate is sized for a Lippert 1621 HD king pin box with a width measurement ("A") of 12-3/4". It shares the same width as the standard 331704 plate but is built with a deeper "B" measurement to accommodate the HD pin box design. SKU: 331711 | UPC: 816456010834
