It reads from 0 to 4-3\/4 inches with an accuracy of 0.005 inches (0.20 mm), making it a reliable hand tool for technicians who need repeatable dimensional measurements on pipe fittings, housings, ports, and mechanical components. The 1-3\/8 inch jaw depth provides reach for stepped or recessed features. A thumb lock secures the sliding jaw once the measurement is set, preventing jaw movement during reading. The bright finish stainless steel construction resists corrosion in field and shop environments.\u003c\/p\u003e\u003cp\u003eThe STARRETT 53124 is suited for HVAC, plumbing, and mechanical service work where dimensional verification is part of the job. Typical applications include checking pipe OD and ID clearances, measuring component housings, and verifying fit of replacement parts before installation. The 1\/4 inch nib size and sliding jaw adjustment make it straightforward to position on irregular surfaces. This caliper is a single-scale vernier instrument — no digital display or dial — which suits users who prefer a tool with no battery dependency and no electronics to protect in the field.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMeasurement range: 0 to 4-3\/4 inches\u003c\/li\u003e\n\u003cli\u003eAccuracy: 0.005 inches (0.20 mm)\u003c\/li\u003e\n\u003cli\u003eStainless steel beam and jaws with bright finish\u003c\/li\u003e\n\u003cli\u003eThumb lock secures sliding jaw at target measurement\u003c\/li\u003e\n\u003cli\u003e1-3\/8 inch jaw depth for recessed or stepped features\u003c\/li\u003e\n\u003cli\u003eSupports inside and outside measurements\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eGeneral-purpose vernier caliper suitable for dimensional measurement tasks across HVAC, plumbing, electrical, and mechanical service trades where measurements fall within the 0 to 4-3\/4 inch range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eNo installation is required. Before use, verify the jaws close fully to zero and confirm the vernier scale reads 0.000 inches with jaws closed. Keep the beam and jaw faces clean and free of debris for accurate readings. Store in a protective case when not in use to prevent jaw damage and scale wear.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Measurement\u003c\/strong\u003e: 0.000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Measurement\u003c\/strong\u003e: 4-3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy (Inch)\u003c\/strong\u003e: 0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy (mm)\u003c\/strong\u003e: 0.20 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJaw Depth\u003c\/strong\u003e: 1-3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNib Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJaw Adjustment Type\u003c\/strong\u003e: Sliding\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Types\u003c\/strong\u003e: Inside, Outside\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes Depth Measurement Rod\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes Inside Diameter Jaws\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFine Adjustment\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThumb Lock\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBeam Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJaw Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: STARRETT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 53124\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51540334739762,"sku":"53124","price":477.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ad9ff143a7f77f480c8106d83ab7427f.jpg?v=1785852460","url":"https:\/\/voomisupply.com\/products\/starrett-53124-vernier-caliper-0-4-75-in-stainless-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
