Direct Chain Connection. Zero Guesswork.\u003c\/p\u003e\n\u003cp\u003eIn overhead lifting, a hook latch that requires manual confirmation is a latch that gets forgotten. The Gunnebo GBK eliminates that risk entirely with the GripLatch system — a self-closing, spring-loaded latch that locks automatically the moment load is applied and stays locked until the hook is unloaded and intentionally released. No manual lock-off. No guessing. A quick visual check confirms closure, and the interlocking design between the latch and hook bowl provides an additional layer of protection against side impacts and accidental disengagement that standard safety latches simply can't match.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDirect to Chain. No Intermediate Link Required.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe GBK's heavy-duty clevis connector attaches directly to Grade 100 or Grade 80 lifting chain — eliminating the need for coupling links and reducing assembly complexity without compromising connection integrity. The clevis geometry also helps prevent mismatched chain connections, reducing the risk of incorrect grade pairing in multi-component sling assemblies.\u003c\/p\u003e\n\u003cp\u003eManufactured from quenched and tempered Grade 100 alloy steel, proof tested to 2.5× WLL, and fatigue rated to 20,000 cycles, the GBK covers chain sizes from 7\/32\" to 5\/8\" with WLL ranging from 3,306 to 22,600 lbs. Every hook carries a heat number stamp for full product traceability and complies with EN 1677:2008 (+25% WLL), ASTM A952\/A952M, and AS 3776:2015 to a 4:1 design factor.\u003c\/p\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWLL Range\u003c\/td\u003e\n\u003ctd\u003e3,306 – 22,600 lbs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChain Size Range\u003c\/td\u003e\n\u003ctd\u003e7\/32\" – 5\/8\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible Chain\u003c\/td\u003e\n\u003ctd\u003eGrade 100 \u0026amp; Grade 80\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eQ\u0026amp;T Grade 100 alloy steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProof Test\u003c\/td\u003e\n\u003ctd\u003e2.5× WLL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFatigue Rating\u003c\/td\u003e\n\u003ctd\u003e20,000 cycles\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDesign Factor\u003c\/td\u003e\n\u003ctd\u003e4:1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLatch\u003c\/td\u003e\n\u003ctd\u003eGripLatch — auto-locks under load\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStandards\u003c\/td\u003e\n\u003ctd\u003eEN 1677:2008 (+25% WLL), ASTM A952\/A952M, AS 3776:2015\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTraceability\u003c\/td\u003e\n\u003ctd\u003eHeat number stamped\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Gunnebo","offers":[{"title":"7\/32\"","offer_id":48077448085722,"sku":"732GBK-6-10","price":195.5,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0825\/8011\/1578\/files\/altu-supply-gunnebo-3-8-gbk-10-10-grade-100-self-closing-hook-8800-lbs-wll-z100760-23__30587_430x_d832e036-63c6-473a-99e1-4fdc02fac13f.jpg?v=1781869528","url":"https:\/\/www.altusupply.com\/products\/gunnebo-grade-100-self-closing-hook-732-gbk-6-10","provider":"ALTU Supply","version":"1.0","type":"link"}
