6' length of top cap piece used to join two polycarbonate panels side by side. Must be used with glazing bar base. 12' and 24' sections are also available, but due to shipping you must call to order.
This extruded aluminum glazing cap will work perfect for my application. Where two pieces of polycarb panels meet, this cap will cover the joint, providing a weather tight seal. Since all the metal trim on my greenhouse is mill finish, this matches perfectly.
