About our Grey Corner Trim for Decking Add perfect clean corners and professional edges to your composite decking project with our coordinating edge trim. Perfectly finishing any rough deck edges, the trim sits over the edge of the deck, covering corners and concealing joins where horizontal decking boards meet vertical fascia boards, hollow board ends or the groove down the side of the decking. The L-shaped edge trims have a bevelled edge to prevent trips and falls and an attractive sanded finish to complement our decking. Easy to install, all of our corner edge trims can be predrilled and screwed through, or for a flawless finish, they can be securely attached with outdoor adhesive. Edging trims are a lower cost alternative to our grey bullnose edging but leave a slight lip over the decking. For a more premium, flush finish, choose bullnose edging.
