Rated at 65 ft\/lb of torque and operating at 90 psi, this tool runs at 350 RPM and accepts a 1\/4 inch NPT air inlet. At 12.4 inches in overall length, it fits the inline handle profile that experienced mechanics rely on for consistent drive angle and reduced hand fatigue during extended fastener work. It is designed for shop and field use where a pneumatic ratchet outperforms hand tools on repetitive fastening tasks.\u003c\/p\u003e\n\u003cp\u003eThe J150RSH is suited for automotive, fleet, and heavy equipment service environments where 1\/2 inch drive pneumatic tools are standard. The inline handle configuration makes it practical for engine bay work, suspension service, and underbody access points where a pistol-grip ratchet may not clear surrounding components. A minimum hose size of 3\/8 inch is required to maintain adequate airflow and consistent tool performance. It is appropriate for use at service bays, dealerships, and mobile repair operations supplied by a compressor delivering at least 90 psi.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2 inch drive with 65 ft\/lb torque output for medium-duty fastener applications\u003c\/li\u003e\n  \u003cli\u003eInline handle design provides a low-profile grip suitable for confined work areas\u003c\/li\u003e\n  \u003cli\u003e350 RPM free speed for efficient fastener cycling\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch NPT air inlet compatible with standard shop fittings\u003c\/li\u003e\n  \u003cli\u003e89 dB rated operation — reference local shop noise exposure guidelines for prolonged use\u003c\/li\u003e\n  \u003cli\u003eCompact 12.4 inch overall length for improved reach in restricted spaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style pneumatic ratchet for use with standard 1\/2 inch drive sockets and accessories.

Before connecting to an air supply, verify that the air line pressure does not exceed 90 psi and that the hose is rated for the required flow. Always disconnect the air supply before changing sockets or performing any maintenance on the tool. Refer to OSHA 29 CFR 1910.242 and the manufacturer guidelines for safe use of portable pneumatic tools in shop environments.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTorque\u003c\/strong\u003e: 65 ft\/lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAir Pressure\u003c\/strong\u003e: 90 psi (6.20 bar)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Speed\u003c\/strong\u003e: 350 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAir Inlet Size\u003c\/strong\u003e: 1\/4 inch NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Hose Size\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 12.4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.9 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Type\u003c\/strong\u003e: Inline\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDecibel Rating\u003c\/strong\u003e: 89 dB\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PROTO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: J150RSH\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51544599888178,"sku":"J150RSH","price":590.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2258567832ffee94ce0d3a806698cda6.jpg?v=1785931050","url":"https:\/\/voomisupply.com\/products\/proto-j150rsh-air-ratchet-1-2-in-drive-65-ft-lb","provider":"Voomi Supply","version":"1.0","type":"link"}
