Security Chain Company QG4221CAM Quik Grip CAM-DT Light Truck Dual and Triple Tire Traction Chain

The Security Chain Company QG4221CAM Quik Grip Type CAM-DT is a heavy-duty dual and triple tire traction chain engineered for light trucks operating on snow and ice. Manufactured to NACM (National Association of Chain Manufacturers) specifications, these chains deliver reliable traction for a wide range of working environments — from highway snow driving to worksites requiring assured grip.

The CAM tightening system uses stamped-steel CAM pieces mounted on the outside rail of the chain. A CAM tool is inserted into the keyhole and turned to take up slack, securing the chain firmly around both tires without the need for separate rubber or spring tensioners. This results in a faster, more secure installation compared to traditional non-CAM designs.

Key Features:

• Type CAM-DT design — engineered specifically for dual and triple rear tire configurations
• Hardened steel construction for maximum durability and long service life
• Cross-chain ladder pattern provides aggressive traction on snow and ice
• CAM self-tightening system eliminates the need for separate tensioners
• Manufactured to NACM chain specifications
• Fits common light truck dual-tire sizes including 235/75-16, 245/70-17, 245/75-16, 215/75-17.5, and 225/70-19.5
• Compatible with tightener QG20069 (sold separately, recommended)

Suitable for light trucks, SUVs, dually pickups, RVs, and commercial vehicles. The QG4221CAM is a go-to solution for fleet operators, tradespeople, and drivers who need dependable winter traction on dual-rear-wheel axles.
