Spacer Seal and Shim Placement
I M P O RTA N T
Your EnCore side rails have had either a spacer seal or shims attached
to provide for easy installation. The spacer or shims help provide a
level sitting rail to enable secure tonneau latching. Please refer
to images below and the guide on the following page per
application or vehicle type to confirm the correct
application of the seals or shims. Some adjustments
may be required to help enable a level rail
once clamped in place.
