Up to two sets are furnished with a Topmaster. Generally, additional frame sets are ordered with the machine.
Banding Wheels
One custom profile banding wheel is provided with the purchase of each Topmaster.The profiled banding wheel is used when the T-molding requires extra support to correctly feed the barb into the slot. Because of the characteristics of certain (high durometer) moldings, not all T-molding need a custom wheel in which case a flat wheel is provided. T-moldings which are either very soft , have a complex profile, or a small radius will require a custom wheel.

The template is sized 1/2″ per side under the actual dimension of the part. most customers provide their own templates although they can be purchased though KRP Manufacturing Inc.
