The Extended Vise Grip Locks are extended bolt versions of the original locks. They are only necessary if you have thick walls, thick door jambs, and/or thick trim.
Measure First Before You Order
You need these only if the measurement from your door jamb (the ridge against which your door closes) to your outer trim is between 4 3/4″ and 6 3/4″ inches (12-17 cm) or 6 3/4″ and 8 3/4″ (17cm – 22cm). They come in sets of two so ordering one of these items in your cart will result in 2 being delivered, one for each side of your Gym1 core unit.
Choose the Vise Grip for your trim thickness from the drop-down menu.
