Loups are ready made soft attachments that replace heavy Stainless Stel shackles on racing and cruising boats. Weight savings on large offshore boats can be as much as 200 lbs. Strong and lightweight Loups are constructed using multiple coils of tough dyneema covered with spetra - one of the most durable materials made. An annealing process ensures loads are equal on all coils. Coloured tracers on the cover specify Loups strength by indicating the number of Dyneema coils. Most loups configurations are made by taking the block apart. If the block can not come apart a pin called a "dogbone" joins the loops to itself. When fitting hardware choose the loops that matches the attachment method shown in the chart.
