Patented snow guard design protects roofing material from damage

Our clamps are designed with a "sliding pin" mechanism, versus a "set screw" system, therefore the AceClamp® does not penetrate the panel material. Plus, they come fully-assembled, saving the contractor on installation time.

Snowguards that install faster and easier

  • Pre-assembled, single-tool clamps
  • No set screws
  • Helps to safeguard panel finish warranty
  • Rigorous third-party load testing
  • Install in about half the time and labor cost!*

Snow Titan® is a heavy-duty snow rail system for areas with extreme snow loads. Originally designed for customers with Kingspan roofs, Snow Titan is capable of up to 42" spans*. Snow Titan snowguards by AceClamp® mean serious business, and feature a triangular rail structure that no other system can match for holding power and strength.
