The Bostik TG4 is a high-end 100-watt glue gun designed for frequent and/or heavy-duty use. It operates at 375F degrees (190 C), which it achieves after only three minutes.

The '08 ULINE catalog listed it as catalog/model number H-181 for $135 U.S. dollars (somewhat less when purchased in sets of two, three, or more). It indicates that the model TG-4 has an output capacity of three to five pounds per hour.

ULINE also offers a variety of clear and amber colored glue sticks, as well as different guns. Other Bostik products include tapes, adhesives, and sealants.
