Made by someone who has done the work
Over 40 years contracting taught me what fails on the job. I invented these products to fix it. My name is on every box. I stand behind it.

From the field
These are not the cheapest insulation fasteners but they are tough. I have not broken one yet and they work great. They invert when you tighten them, then they are flush with the insulation surface.
They are a super great product. Our installation technicians are using them on almost every job and they love them!!!
Ordered these for a HVAC company and they were exactly what we needed. The shipping was on time. I would order from JT Products again.
