We are a leader in providing high-performance, superior quality clamps, strut, U-bolts, and quick disconnect products.

In the HVAC/R business time you don't want to run hot and cold on the jobsite. Instead, you want to be confident every job is running efficiently. And you want to make sure the clamps, strut, saddles, fasteners and quick disconnects you're using can withstand extreme temperatures.

Looking for extremely durable heat- and cold-resistant cushioned clamps? The ZSI-Foster Cush-A-Nator Extreme Temp services temps from -65°F - 340°F and provides longer life against vibration fatigue. It's made from a proprietary thermoplastic vulcanized material cross-linked with high performance rubber and thermoplastic elastomers. This combination produces the highest operating temperature range in the industry.

The Cush-A-Nator is also offered in a standard temp version, -50°F - 275°F, at the same price as the original Cush-A-Clamp.

The Cush-A-Nator is the easiest cushioned clamp system to install because you can lay pipe runs first, add clamps second. It also makes retrofits a breeze since clamps and cushions can be replaced without moving pipe.

You can count on us to provide the high-quality products you need for your HVACR installations

Whether you're looking for cushioned clamps to prevent corrosion or vibration, quick disconnects couplers or hose fittings or clamps for crush-resistant airtight seals, ZSI-Foster can help.

For example…

  • Cush-a-Claw grabs your tube, pipe or hose and holds it in place. A unique one-piece design allows for quick and simple installation. The Cush-A-Claw is ideal for lighter vibration and is designed to withstand a corrosive environment. It will not rust.
  • The Cush-A-Block Rooftop Support System is UV resistant and suitable for installation on most types of roofing material or other flat surfaces. Designed to dampen vibration it's resistant to freeze and thaw and features a built-in channel to easily install strut straight.
  • Our Cush-A-Glide is designed for fast installation of copper tube or pipe. Spread the clamp apart, placing over tube or pipe, and fasten one side. Push in the opposite side to the desired tightness, allowing for expansion and contraction, then fasten the other side.

Because we recognize the HVAC/R industry needs products which can handle a wider temperature range, we now offer our popular clamps such as the Alpha U-Bolt and Omega Clamps in Extreme Temp versions.

Our team of professionals is reliable and fast to respond. If you need a product designed to meet your unique specifications, we can work with you to develop one. Not sure what you need? Just ask. Our team is always ready to provide the support you need to make the right decision.

  • "…don't know what I'd do without the Cush-A-Glide."
