The Ulmia Miter Clamp pliers are used to apply all 6 sizes of clamping rings.
The Miter Clamp System by Ulmia is the original German version of an incredibly useful type of clamping tool. Works great for mitered joints such as casing, crown moldings, picture frames as well as holding parts together for assembly. The plier tool makes positioning and applying the clamp an easy precise one hand operation. The clamp puts just enough pressure on your miters to create a perfect glue joint that won’t fail. The sharpened ends of the clamp rings hold securely in any wood. Clamping blocks can be attached with hot glue or double sided tape to protect finished surfaces. Spring steel rings are available in 6 different sizes, applied with the special pliers. Also available as a set. Set includes 1 pair pliers, 8 rings each size A to F, total of 48 rings, all in fitted plastic carrier, with or without fitted wooden box.
