The 3/8 inch Expansion Joint Black is a movement trim by Resin Rock, engineered to bridge control or expansion joints in concrete slabs and carry that movement up through resin-bound surfaces without cracking the finish.

Each piece pairs rigid aluminum anchoring legs with a flexible black PVC insert down the center. As the surface expands and contracts with temperature changes, the insert flexes and keeps the resin-bound topping intact.

• Aluminum Anchoring Legs - rigid alloy legs bed firmly into the resin-bound layer
• Flexible Black PVC Insert - center channel absorbs thermal and structural movement
• 3/8 Inch Profile - sized to finish flush with a thinner resin-bound surface
• 8 ft Length - long, continuous pieces for clean joint lines
• Edge Protection - side legs protect surface edges along the joint

Match profile height to your resin-bound system depth for a flush, professional finish.
