The HPRC Tripod Support Platform is designed to mount on top of a standard tripod that uses a 3/8" tripod screw. Once attached, it folds out flat and creates a solid platform to put a laptop or paperwork on. The adjustable wings help to hold the items securely and it folds out quickly and easily for rapid set up and storage making it a reliable support for your laptop, projector or a HPRC Hard Resin Case. It has been designed to take the 2400 range upto the 2550W, so is really useful as an all in one stand for keen photographers. It has been made from a combination of ABS and stainless steel, so it has been built to last, as you would expect from this company.
