Hi. This is Kyle from APS and I'm here to share with you some of the characteristics of Poly Tec SK-78 line from New England. It's available in 1/4, 5/16 and 3/8, and in these three colors. It is a double braid construction. The jacket is a mix of polyester and Technora. The Technora is, being much more abrasion resistant than polyester and most of their fibers makes this an excellent line to upgrade to if you've got an existing line that's being eaten up in a clutch or on a wench, like a runner or a sheet. You're going to get a lot longer serviceable life with that Technora blend in that jacket.

The cores are the SK-78 Dyneema. They are coated so that you can strip the jacket, bury it, if you want to expose the working end and reduce the weight on the working end of the line. If you do an eye splice it would be a high tech eye splice. This is the quarter inch, maybe slightly on the stiff side, but that could be just the coating on the core. The core, kind of a medium to almost slightly a tight braid angle. Moving up to the 5/16, again we see a pretty tight braid angle on the core. Moving up to the 3/8, a slightly more open braid angle on that core.

That's Poly Tec SK-78 by New England. For these and all of your line needs visit us at apsltd.com.
