We offer several different sizes of superior quality, thin-wall silicone rubber corner tubeseal to assure perfect sealing of any gap from 1/64″ to 3/8″ with virtually no noticeable increase in closing pressure.  Tubeseal features a friction-grip foot designed to fit a 1/8″ wide straight groove kerf cut.

** We offer the WS98 Corner Grooving Machine as a special purchase item.  Drill bits specifically designed for the tubeseal weather strip are available with the WS98 or can be purchased separately.  All options may be added to your free quote, or please call.
