It features a 1\/2-13 thread size with a thread length of 0.43 inches and a plunger diameter of 0.31 inches. The spring-loaded plunger delivers an initial end force of 1 pound and a final end force of 4 pounds, making it suitable for light-duty retention tasks. The pull ring allows the plunger to be retracted manually without additional tooling. Installed by machinists, maintenance technicians, and mechanical assemblers, this plunger is a standard hardware component in jigs, fixtures, and equipment panels.\u003c\/p\u003e\n\u003cp\u003eThe PR50-G is used in industrial and commercial mechanical assemblies where a repeatable, spring-loaded detent or stop point is needed. It threads directly into tapped holes and is pulled to disengage, then spring-returns to the locked detent position. Typical applications include fixture plates, machine guarding panels, equipment enclosures, and tooling setups where quick manual disengagement is required without tools.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNon-locking pull ring design allows manual plunger retraction without tooling\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 thread size with 0.43-inch thread length for standard tapped-hole installation\u003c\/li\u003e\n  \u003cli\u003eSpring force range: 1 pound initial to 4 pounds final end force\u003c\/li\u003e\n  \u003cli\u003ePlunger diameter of 0.31 inches and plunger projection of 0.38 inches\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in industrial environments\u003c\/li\u003e\n  \u003cli\u003eCompact body length of 0.81 inches suits space-constrained assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-thread replacement or new-installation pull ring plunger for mechanical assemblies with a 1\/2-13 tapped hole and clearance for a 1-inch ring diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by threading the PR50-G into a 1\/2-13 tapped hole using a wrench on the 0.5-inch hex head. De-energize or lock out any equipment before installing or replacing plungers in active machinery per applicable OSHA lockout\/tagout procedures. Do not exceed the rated end force by forcing the plunger beyond its designed projection range. Verify thread engagement depth against the 0.43-inch thread length to ensure secure seating in the mating component.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.43 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Diameter\u003c\/strong\u003e: 0.31 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 0.38 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Length\u003c\/strong\u003e: 1.06 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 0.81 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 0.56 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRing Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 4 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Type\u003c\/strong\u003e: Non-Locking\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLocking Element\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: GIBRALTAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: PR50-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51721443574066,"sku":"PR50-G","price":20.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8f5ffd0b18eb016cfab4c26a7de75850.jpg?v=1788577486","url":"https:\/\/voomisupply.com\/products\/gibraltar-pr50-g-pull-ring-plunger-1-2-13-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
