Heavy Duty TBA/TBB Clamps
Murray heavy-duty T-Bolt Band clamps are designed to provide connections without leaks in applications that require additional installation torque and strength. Typically used in agriculture, center pivot irrigation, marine, heavy-duty truck, and severe service industrial applications. Available in two styles:
- TBA Series: Welded band tongue under the bolt
- TBB Series: Floating “channel” bridge under the bolt
- Both TBA and TBB series have 5/16″ diameter bolts, .875″ wide, and .040″ thick bands, providing a considerably heavier-duty construction than standard T-Bolt band clamps.
Heat-treated alloy steel bolts and self-locking nuts are double plated clear chromate finished for high corrosion resistance. All other clamp components are 300 series bright finished stainless steel.
