Apr 26, 2017 Stainless steel lacing buttons and mushrooms New in stock , we have a lovely range of Stainless steel lacing buttons made from marine grade 316 A4 stainless steel. We have a number of different styles to suit all canopy and sprayhood needs. The main usage for these lacing buttons are to hold down shockcord and bungee cord to keep the bimini or boat canopy nice and tight but yet with the use of bungee cord there will be a little room for movement when the wind picks up which will help the canopy prolong its life rather than being fixed to the deck with a fastener. All can be found here on our website http://www.jclarkemarine.com/collections/hooks-and-bridges
