One trim for awkward angles. J380 is a flexible internal angle trim designed to follow variable angles, so you can bridge non-true corners, splayed upstands, and transitions without fighting the laminate. Great for refurb and detail work where nothing is perfectly square. 

Why roofers pick it

• Follows the building, not the brochure: flexes to suit real-world angles.
• Cleaner lay-ups: a guided curve helps resin and CSM seat evenly through the turn.
• System fit: adhesive + pins, bandage fixings, laminate with RORR, topcoat grey.

Install notes

• Offer up and form to the angle, bead PU adhesive, pin sparingly, bandage nail line, then laminate deck → trim → face.

Specs (typical)

• Length: 3 m | Working angle window: ~35°–50° from flat | Nominal section: ~85 × 300 mm.
