It delivers up to 1,980 pounds of clamping pressure through a 0.7-inch diameter high carbon steel spindle, giving trades workers a firm, repeatable hold across a wide range of workpieces. The 8-inch maximum capacity and 4-3\/4-inch throat depth accommodate both shallow and moderately deep clamping setups. The electrogalvanized steel frame resists corrosion in shop environments. The composite T-handle provides a controlled grip during tightening without requiring separate tools.\u003c\/p\u003e\n\u003cp\u003eThe 1800-S8 is suited for residential and commercial shop use, on-site framing and millwork tasks, and bench assembly operations. The sliding arm design allows rapid jaw positioning before final clamping, reducing setup time when working with multiple pieces. The patented 1-3\/32 inch by 7\/16 inch rail profile adds torsional stiffness to the bar, helping maintain alignment under load. This clamp is appropriate for use by carpenters, ironworkers, fabricators, and general contractors requiring a reliable, mid-capacity bar clamp on the job.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1,980 pounds of clamping pressure for demanding hold requirements\u003c\/li\u003e\n  \u003cli\u003ePatented rail profile (1-3\/32 inches by 7\/16 inches) resists twist and flex under load\u003c\/li\u003e\n  \u003cli\u003e0.7-inch high carbon steel spindle for durability and precise pressure application\u003c\/li\u003e\n  \u003cli\u003eElectrogalvanized steel frame and steel MorPad for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eErgonomic BESSEY composite T-handle grip for controlled tightening\u003c\/li\u003e\n  \u003cli\u003eSliding arm allows fast jaw positioning across the full 8-inch capacity range\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct addition within the BESSEY 1800-S Series.

Before applying clamping pressure, confirm workpiece surfaces are clean and free of debris to prevent marring or slippage under load. Use appropriate personal protective equipment when working with high-clamping-force tools, particularly in metal fabrication environments. Inspect the spindle threads and sliding arm mechanism for wear or damage before each use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClamp Type\u003c\/strong\u003e: F-Style Sliding Arm Bar Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Capacity\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThroat Depth\u003c\/strong\u003e: 4-3\/4 inches (4.75 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClamping Pressure\u003c\/strong\u003e: 1,980 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpindle Diameter\u003c\/strong\u003e: 0.7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpindle Material\u003c\/strong\u003e: High Carbon Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRail Size\u003c\/strong\u003e: 1-3\/32 inches by 7\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRail Length\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFrame Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePad Material\u003c\/strong\u003e: Steel (MorPad)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePad Type\u003c\/strong\u003e: Medium Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Style\u003c\/strong\u003e: T-Handle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Material\u003c\/strong\u003e: Composite\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Electrogalvanized\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Ergonomic BESSEY Grip, MorPad, Patented Rail Profile\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1800-S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112100\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: BESSEY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1800-S8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BESSEY","offers":[{"title":"Default Title","offer_id":51539295469874,"sku":"1800-S8","price":128.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5ef82d0af11428accea7a07cfbd7a086.jpg?v=1785837982","url":"https:\/\/voomisupply.com\/products\/bessey-1800-s8-sliding-arm-bar-clamp-8-in-4-3-4-in-throat","provider":"Voomi Supply","version":"1.0","type":"link"}
