This kit is perfect for the glass shop that needs to produce insulating glass units on an occasional "as needed" basis, or for someone who needs to do their work in different locations from time to time. The CRL "Hardman" Insulating Glass Hot Melt Butyl Starter Kit is also a great way to start a small production system for fabricating I.G. units. Everything you need to get started in I.G. unit production is included in this kit. The only thing you need is the glass and a clean, flat table for fabrication. This system even includes a shoulder strap, which reduces operator fatigue, and supports the Hot Melt Extruder Gun while you work.Kit Includes:
