Is it hard to know what your Band-It band clamp is tight. The method described below will help you to indicate when
a band clamp has reached its maximum holding force. The point of maximum holding force may be too
tight for some objects and not tight enough for others. BAND-IT® cannot provide a method to tell if a clamp
has been applied too tight or too loose. BAND-IT® always recommends testing as the only measure to
determine if tightness is appropriate for the application.
When steel band is tensioned up to its “yield strength” it has maximum holding force. Additional tensioning
beyond the yield strength will stretch the band but not apply additional holding force. If tensioning and
stretching continues the band will, ultimately, break.
The key is to get consistently close to the band’s “yield strength” without significantly stretching
How to determine if a band has reached its “yield strength”:
1. Insert the clamp tail into the tensioning tool. Tension until the clamp is snug.
2. Using a felt tip marker, place 3 or 4 lines across the band clamp, about ¼” in front of the buckle.
3. Resume tensioning and watch for movement of the lines in relation to the buckle.
The clamp has reached its yield strength when the lines stop moving. STOP! It will not achieve additional
holding force and if tensioning and stretching continues, the band will weaken. Further tensioning of the
clamp may result in band failure. Galvanized carbon steel band has less strength than stainless steel.

Band-It Clamping company manufactures several mounting Brack-It’s for mounting signs securely. Choosing the correct mounting hardware significantly reduces call backs due to sign shifting. Wind, vibration and other environmental factors are things to consider before installation. All Band-It Brack-It’s are manufactured with high strength stainless steel and metal forming technology that adds reinforced fibbing for addition stiffness. Our goal is to simplify which Brack-It is used for your specific application.
The Flair Leg BRACK-IT design provides a secure fit that locks each leg in
place on round poles or mast arms of almost every diameter.
• Use the D31099 single bolt, flaired leg Mini- BRACK-IT and 1/2″ band
when the post is less than 3 1/2″ diameter and signs are less than 3
• Use the D02189 single bolt Flaired Leg BRACK-IT and ¾” band when
mounting on round posts greater than 3 1/2” or with larger signs.
Straight Leg BRACK-IT design should be used when mounting a sign on a flat
surface or to straddle the shape of fluted poles.
• Use the D31599 single bolt, Straight Leg Mini BRACK-IT and ½” band
when the signs are less than 3 square feet.
• Use the D00189 and ¾” band for larger signs.
• For greater sign support surface area and holding force use the D00889
2-bolt straight leg BRACK-IT.
