What is the difference between a groove top frame and a wedge top frame?
The groove or wedge in the frame refers to the top bar. A grooved top bar has a groove for inserting your foundation. It is generally used with plastic foundation such as Rite-Cell ®. Wedge top frames look similar, however, they have a piece of wood next to the groove that you would break off to install your wax foundation. The wedge piece is removed and your wax foundation is put in place. The wedge is then re-inserted and nailed in place. The purpose of the wedge is to give support to your wax foundation. Wax foundation will also need support from wire, support pins, or both. If you are using wired foundation with hook, the hook is placed so it goes around the wedge piece like a hanger on a rod.
