About these items These chain tensioners offer load capacities ranging from 2,200 kg to 4,172 kg, suitable for securing cargo on trucks, trailers, agricultural applications, or marine applications. They include G80 chains with breaking strengths of up to 13,600 kg, providing the strength needed to tie down, strap down, or tow heavy loads without compromising safety. Compatibility includes 5/16", 3/8", and 1/2" chains, allowing these tensioners to be used in a variety of situations depending on the type of load and vehicle. Each kit includes forged hooks at both ends, ensuring a secure hold. Some models offer length adjustment from 57.5 cm to 77.5 cm for precise tensioning. The 33 to 40 cm handles feature textured or knurled rubber grips, ideal for sweaty hands or use with gloves. Thanks to their lever construction or ratchet mechanism, tensioning or releasing chains is effortless, optimizing time and energy for each task. Made of cast steel, carbon steel, or alloy steel, these tensioners are powder-coated or galvanized, offering high resistance to adverse weather conditions. Their solid construction ensures durability for long-term use, especially in transportation, construction, or field environments. Designed to comply with CVSA, DOT, NACM, and FMCSA regulations, these tensioners are easy to install and disassemble. Turnbuckles are suitable for securing loads in land transport, forestry, agriculture, maritime, and warehousing. They are an indispensable tool in operations where load safety and stability are a priority.
