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 200 lb (91 kg).
Strong and lightweight, LOUPS™ are constructed using multiple coils
of tough Dyneema® covered with Spectra®-one of the most durable
materials made. An annealing process ensures loads are equal on all
coils. Colored 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't be opened a pin called a "Dogbone" joins the LOUPS™
