This our our Fold flat frame. It has a solid oak base that has a small try in it for tools and rubber no slip on the bottom to hold the frame securely in place on your lap or on the table in front of you. The tops are made from oak and are rounded so the grippers are open and spread to hold your backing. If you have ever tried a flat top frame and had trouble with the backing staying on this is why. The grippers MUST be on a curve in order to work 100%, they will hold if stapled on a flat surface, but not as much as on a curve. Our frames are all top quality and we stand behind them 100%. This head does not swivel, but it does tilt so that you can hook at the most comfortable position for you. I can't say enough good things about our frames and neither can our happy customers. The head is 17x15 with a 15x13 Hooking area.
