Proto JSCVT-20S Ratcheting Combo Wrench Set 20 Pc Inch

Product Description

The PROTO JSCVT-20S is a 20-piece reversible ratcheting combination wrench set designed for professional trade use in mechanical, HVAC, plumbing, and electrical service work. Each wrench features a 12-point ratcheting box end with a 15-degree head offset angle, allowing operation in tight spaces where a standard combination wrench cannot swing a full arc. The chrome-plated finish resists corrosion and wipe-down contamination common in service environments. The full set covers 20 inch fractional sizes and ships stored in a tool roll for organized transport to job sites. Total set weight is 15.62 pounds.

This set is suited for residential and commercial service technicians who need a complete inch fractional wrench range in a single organized package. The reversible ratcheting mechanism eliminates the need to remove and reposition the wrench between strokes, which improves efficiency on fastener-dense equipment such as air handlers, condensing units, boiler assemblies, and electrical panel work. The tool roll format makes the set practical for field service vans and tool bags where drawer space is not available.

Installation Notes

Ratcheting combination wrenches are used by licensed HVAC technicians, plumbers, electricians, and mechanical contractors for fastener work on equipment and piping systems. Always de-energize electrical equipment and shut off gas or fluid supply lines before beginning service work that requires wrench access to system components. Inspect the ratcheting mechanism before each use and do not use a damaged or slipping wrench on torque-critical fasteners. No power tools are required to use this set.
