For macro stacking and multi-row panorama shooters, saving time when reassembling hardware configurations in the field is vital. When fastened to a G015 or G016 series rail, this indexing bar serves as a physical, unyielding boundary, allowing you to slide a quick-release clamp to the exact millimeter position needed without tedious measuring.\u003c\/p\u003e \n    \n    \u003cp style=\"font-size:14px; margin-bottom:15px;\"\u003eBeyond its utility as a rail index component, this stop bar functions as a high-security anti-twist ridge. Standard camera feet or lens collars that rely on a single 1\/4-20 mounting screw are notorious for slipping and rotating out of alignment over time. By combining this stop bar with an M1 series camera plate, you form a custom-fit mechanical lip. This ridge physically cradles the flat side of a single-hole lens foot, distributing the rotational torque across the entire aluminum plate and locking your gear into a static position.\u003c\/p\u003e \n    \n    \u003cp style=\"font-size:14px;\"\u003eMachined from a solid block of aircraft-grade 6061-T6 aluminum and protected by a rich black hard-coat anodize, this hardware block is built to endure constant pressure and weather exposure. It is a highly practical, modular asset that protects your premium optical equipment while accelerating your workflow efficiency.\u003c\/p\u003e \n\u003c\/div\u003e","brand":"Hejnar Photo","offers":[{"title":"Default Title","offer_id":67701623980137,"sku":"Stop-Bar-Screw-On-Package","price":10.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0794\/1278\/9353\/files\/Stop-Bar-Screw-On-Package-2.jpg?v=1792111697","url":"https:\/\/www.hejnarphotostore.com\/products\/screw-on-index-stop-bar-anti-twist-ridge","provider":"Hejnar Photo","version":"1.0","type":"link"}
