General AceClamp Related FAQ's

Most of my installers use hammer drills – they are faster than power screw guns. 
We don’t recommend tightening the AceClamps with hammer drills. AceClamps are designed with anti-backout features so that vibrations common to wind flutter along coastal regions and seismic activity on the west coast preventing AceClamps from loosening. The action of a hammer drill may damage the locking mechanisms allowing the clamp to loosen over time.

How do I know what torque to use?
Check the manufacturer’s instructions and data sheet for the recommended torque based on the roof panel type and material thickness. Questions? Contact AceClamp engineering.

Can I use AceClamps and the snow rail for fall protection?
Although we have one of the strongest clamps in the business, we have not specifically tested AceClamps for fall protection and discourage customers from using it in this manner.

How do I know which product I need?
Contact AceClamp for a custom engineered layout and product suggestion based on snow load.

How do I determine my snow load?
AceClamp will help in determining the snow load based on a few factors like project location, type of panel, slope, and size of the roof. Best to leave this job to the professional.

Will your clamps fit my roof?
AceClamp has a solution for most roofing profiles. Provide your panel manufacturer and model, or a picture and we will suggest the appropriate clamp for you.

How do I know your clamps will hold?
AceClamp rigorously tests all our clamps with a third party to ensure they will perform through the harshest conditions.
