{"title":"High Load Blocks for Dinghies","description":"\u003cp\u003eSeldén BBB25 high load ball bearing blocks in single, double and triple sheave configurations, all-stainless construction rated for wire and rope up to 5 mm, suited to halyards, control line tackles and compact purchase systems on smaller dinghies.\u003c\/p\u003e\n\u003ch2\u003eHow to choose\u003c\/h2\u003e\n\u003cp\u003eThe BBB25 is a specialist block designed for high load relative to its size. Unlike the standard BBB range where sheave diameter follows line size, the BBB25 is built around an all-stainless steel construction with stainless ball bearings and ball cages, making it significantly stronger than its 25 mm sheave size suggests. It handles wire and rope up to 5 mm and is the right choice where a compact, strong block is needed and space or weight is at a premium.\u003c\/p\u003e\n\u003cp\u003eTypical applications are halyard tackles, control line purchase systems and anywhere a high-load block needs to fit into a tight space on a small dinghy. It is not the right choice as a mainsheet block on larger boats, the standard BBB30, BBB40 or BBB60 range handles larger line diameters and is better matched to mainsheet loads.\u003c\/p\u003e\n\u003cp\u003eFor singles, choose the attachment type to match your fitting point. The strap loop version attaches with a shackle or line through the loop. The fixed pin version mounts with a tie-on lashing. The removable pin version allows the block to be detached quickly without tools. The becket with removable pin adds a secondary attachment point for anchoring the standing end of a purchase system.\u003c\/p\u003e\n\u003cp\u003eFor doubles and triples, both are available with and without a becket. Add a becket when the standing end of the tackle returns to the block. The triple strap and triple becket strap are suited to higher purchase systems in compact applications where a larger block series would be too bulky.\u003c\/p\u003e\n\n\u003ch2\u003eWhat's in this collection\u003c\/h2\u003e\n\u003cp\u003eThe \u003cstrong\u003eBBB25 single range\u003c\/strong\u003e covers lines up to 5 mm and includes four attachment options: strap loop (402-201-04R), fixed pin with tie-on attachment (402-201-05R), removable pin (402-201-06R) and becket with removable pin (402-201-07R).\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003eBBB25 double range\u003c\/strong\u003e covers lines up to 5 mm and is available as a strap double (402-201-08R) and a becket strap double (402-201-09R).\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003eBBB25 triple range\u003c\/strong\u003e covers lines up to 5 mm and is available as a strap triple (402-201-10R) and a becket strap triple (402-201-11R).\u003c\/p\u003e\n","products":[{"product_id":"25-mm-high-load-ball-bearing-block-single-strap","title":"25 mm High Load Ball Bearing Block - Single, Strap","description":"\u003cp\u003eThe BBB25 Single Loop Block is a 25mm high load ball bearing block designed for dynamic loads on smaller boats.
