Will the end caps work with another decking brand?
It would be difficult to say for sure, as we do not know the dimensions of the other brand decking boards. These end caps are designed to work with NewTechWood hollow decking with the dimensions in this diagram: https://www.newtechwood.com/img/decking/profile/decking-uh02.jpg. You may check if the dimensions of the other brand would be the same. You may also purchase a bag, or request a sample, of an end cap to test before purchasing the total quantity needed to complete your deck.
