The Tiger Claw TC-G is much better than the vertical Trex plastic universal hidden fastener. Because it is screwed in with 45 degree, it actually tights the board to the last one and it will keep the gap between boards the same. With Trex plastic universal one, you have to have another person to push the board next to the last one; it is very difficult to keep the gap between the boards the same. With Tiger claw TC-G, you can install the board by yourself and can finish the job much faster. Highly recommended. BTW, shipping is very fast and very happy with the purchase.
