The Easy Trim End Cap is the finishing touch to Easy Trim Dry Verge. Fitted in where two verges meet the ridge of a roof, the end cap seals any possible gaps away from water, snow, and any unwelcome insect visitors. Designed to be used with Easy Trim Dry Verge kits. All Easy Trim Dry Verge materials are primarily composed of polypropylene. The FlapCap system allows for a super-secure seal.
