Tectran Manufacturing's Extreme Duty Tender Kits, Nos. 7480SS and 7481SS, are cost effective and durable, perfect for heavy-duty work. The kits include a stainless steel snap clip that attaches to slide bars up to 1" in diameter as well as an SS carabiner. The heavy-gauge springs can suspend hydraulic hoses and are RoHS compliant and zinc-plated for corrosion resistance, while the blue sleeves are attached with stainless-steel hardware, completely cover the spring when it is collapsed, and feature rolled edges for crack resistance. The 16" and 25" spring rates can be matched without overpowering each other.
