Product catalog summary

Overview: Murray Heavy-Duty T-Bolt band clamps are engineered for leak-proof connections in high-torque and strength-demanding applications. They are commonly used in agriculture, marine, heavy-duty trucking, and severe industrial services.

Product Specifications:

Available in two styles: TBA and TBB series.
Both series feature 5/16” diameter bolts, .875” wide, and .040” thick bands, offering a robust construction compared to standard T-Bolt clamps.
Components include heat-treated alloy steel bolts and self-locking nuts with a double-plated clear chromate finish for enhanced corrosion resistance. Other parts are made from 300 series bright finished stainless steel.

Series Details:

TBA Series: Features a welded band tongue under the bolt.
TBB Series: Includes a floating “channel” bridge under the bolt.
