Pewag Servo RS 68 Self-Tensioning Snow Tire Chains Pewag snow chains are clever Tensioning systems for snow chains have to get more conve- nient: This was pewag’s main goal when developing the latest generation of automatic ratchets. The key objective was to make mounting the chains easier by enhancing the tensioning system, and to improve performance and user friendliness. We created the new servo-technology to achieve these objectives. Pewag servo was developed for vehicles with high powered engines and offers the ease of stationary mounting and reliability under all conditions. Due to its low profile pattern for class “S” applications; Pewag Servo allows for vehicle clearance, perfect traction, and a long life span. •High quality chain with innovative technology •pewag servo ratchet tensions the chain automatically - manual tensioning is not necessary •Always pre-fit chains before use Qualified Discount: Vet/Senior, Business or Gov’t call 800 770-0077 •pewag servo ratchet tensions the chain automatically - manual tensioning is not necessary •Always pre-fit chains before use Qualified Discount: Vet/Senior, Business or Gov’t call 800 770-0077
