Harken LOUPS Ready-Made Rigging Attachments -
LOUPS are ready-made soft attachments that replace heavy stainless steel shackles on racing and cruising boats. Weight savings on large offshore boats can be as much as 200lb. (91kg). They're strong and light, constructed of multiple coils of tough Dyneema® covered with Spectra® one of the most durable materials made. An annealing process equalizes the load on all coils. Colored tracers on the cover specify LOUPS strength by indicating the number of Dyneema® coils. Most LOUPS configurations are created by taking the block apart, or if the block can't be opened, by using a pin called a "Dogbone" to join the LOUP to itself. When fitting hardware, choose the LOUPS that matches the attachment method shown in the chart.
