Twist the body to shorten or lengthen it and take up slack. Sold singly.\u003c\/p\u003e\n\u003cp\u003eThe same 316 grade we use on \u003ca href=\"\/products\/the-stainless-one\"\u003eThe Stainless One\u003c\/a\u003e — rust and corrosion resistant, and it will still turn freely in a few years rather than seizing solid, which is the usual fate of cheaper tensioners left outdoors.\u003c\/p\u003e\n\u003ch3\u003eShade sails\u003c\/h3\u003e\n\u003cp\u003eThe main job. A slack sail flaps, and flapping is what destroys them — every gust works the stitching and the corner rings, and a sail left loose through a windy autumn will not see many summers. Tensioned properly it sits still and sheds water instead of pooling it.\u003c\/p\u003e\n\u003cp\u003eFabric also stretches over the first few weeks, and a turnbuckle lets you take that up in seconds rather than unhooking and re-rigging the whole thing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOne per corner\u003c\/strong\u003e — three for a triangular sail, four for a square one.

Do not go further.\u003c\/p\u003e\n\u003cp\u003eIt is tempting to keep twisting until the line is drum tight, and we would not recommend it. A taut line has nowhere to give, so every gust and every load goes straight into the posts at either end. Poles are strong, but they are not immune to being levered on day after day. A line with a little natural droop in it is doing its job properly and is kinder to everything it is attached to.\u003c\/p\u003e\n\u003cp\u003eThe same applies to a sail: firm and still, not stretched.\u003c\/p\u003e","brand":"The Washing Line Pole Shop","offers":[{"title":"Default Title","offer_id":55149413892425,"sku":null,"price":8.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1027\/8974\/2921\/files\/shade-sail-tension-turnbuckle.jpg?v=1787815154","url":"https:\/\/washinglinepoles.co.uk\/products\/shade-sail-tension-turnbuckle","provider":"The Washing Line Pole Shop","version":"1.0","type":"link"}
