The side plates are hot-forged aluminum for maximum strength and rope-friendly rounded edges with a high-wall design that protects your rope and sling from touching the tree. The precision CNC machined aluminum sheaves have a wide bend radius to reduce the rope strength lost when bending, and have a 150kN MBS. The low-profile spring pin lock features a secure, two-stage locking motion with a spring that allows you to lock and unlock your block easily while wearing gloves.\u003cbr\u003e\nMBS: 150kN\u003cbr\u003e\nWLL: 30kN\u003cbr\u003e\nMax Rope Diameter: 3\/4\"\u003cbr\u003e\nMax Anchor Sling Diameter: 1⅛”\u003cbr\u003e\nSuper rope-friendly design\u003cbr\u003e\nHot-forged aluminum side plates with rope-friendly rounded cheeks\u003cbr\u003e\nPrecision CNC machined aluminum high-efficiency sheaves\u003cbr\u003e\nLow-profile, secure, easy-open, two-stage captive spring pin lock\u003cbr\u003e\nHigh-wall, full-diameter, improved anchor sling protection\u003cbr\u003e\nFlared side plates reduce twisting in complex rigging scenarios\u003c\/p\u003e","brand":"Notch","offers":[{"title":"3\/4\"","offer_id":42216978972854,"sku":"56130 \/ 12372","price":188.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0269\/4148\/9232\/products\/56130-1.png?v=1747372305"},{"product_id":"notch-1-2-rigging-block","title":"Notch 1\/2\" Rigging Block","description":"\u003ch1\u003e\u003cspan style=\"font-size: 18px;\"\u003eNotch 1\/2\" Rigging Block\u003c\/span\u003e\u003c\/h1\u003e\n\u003csection\u003e\n\u003cp\u003eThe Notch 1\/2\" Rigging Block is a small sized lightweight arborist block accepts working lines up to 1\/2” (13mm) diameter.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHot forged aluminum side plates with rope friendly rounded cheeks\u003c\/li\u003e\n\u003cli\u003ePrecision CNC machined aluminum sheaves with wide bend radii\u003c\/li\u003e\n\u003cli\u003eLow profile, secure, easy to-open captive screw pin lock\u003c\/li\u003e\n\u003cli\u003eHigh wall, full diameter, improved anchor sling protection\u003c\/li\u003e\n\u003cli\u003eWide, concave upper sheave accepts 5\/8” anchor slings\u003c\/li\u003e\n\u003cli\u003eFlared side-plates reduce twisting in complex rigging scenarios\u003c\/li\u003e\n\u003cli\u003eWORKING LOAD LIMIT:  (WLL) 20 kN (4,496 lbs.)\u003c\/li\u003e\n\u003cli\u003eMBS:  100 kN (22,480 lbs.)\u003c\/li\u003e\n\u003cli\u003eMAX WORKING LINE DIAMETER:  1\/2 in (13mm)\u003c\/li\u003e\n\u003cli\u003eMAX SLING DIAMETER:  5\/8 in (16mm)\u003c\/li\u003e\n\u003cli\u003eUPPER SHEAVE DIAMETER:  .75 in (19mm)\u003c\/li\u003e\n\u003cli\u003eLOWER SHEAVE DIAMETER: 1.5 in (38mm)\u003c\/li\u003e\n\u003cli\u003eHEIGHT:  4.7 in (118mm)\u003c\/li\u003e\n\u003cli\u003eWIDTH:  2.7 in (68mm)\u003c\/li\u003e\n\u003cli\u003eWEIGHT:  1 lb.
