Line Splicing Tips and Techniques

A finger trap is the most common, and strongest method of joining 2 sections of line, or placing an eye in the end of the line. There are a few different tricks for manipulating the line, but by far the easiest is to use a small aluminum splicing fid. After trying most of the splicing tools available, we determined that most of the tools available were designed for line much larger than what is typically used for towing either paragliders or hang gliders. Those that were small enough were cheaply made from plastic and held the line poorly, or wore out quickly. We knew there had to be a better tool, so we used our CNC machines to build a splicing fid to our high standards. TowMeUp.com manufactures a Fid specifically for each size line we carry. If you happen to have a special line size, feel free to contact us, since we can quickly manufacture one for most any size or application using our CNC equipment. Splicing fids are custom made from 7075 Aluminum solid bar stock, heat treated, and anodized. The internal threads are cut, rather than rolled so they grip Spectra, Technora, Polyester, Polypropylene, or Kevlar line firmly. For custom sizes that we do not stock, we REQUIRE you to send us a sample of line to enable us to design and fabricate a fid that will work properly for your application.

Please note though that we only know exactly what size fid is the correct one for the line products that we carry in stock. Not all Spectra is easily spliceable. Samson, or Amsteel line for example is VERY DIFFICULT to splice, even when using our fids. The best way to ensure we can get you the right size fid is to send us a short sample of the line you wish to splice and we will attempt to splice it and tell you the best fid to use, if it is even possible to splice.

If you bought your towline from another vendor and find it almost impossible to splice it's helpful to know that you're not alone. It's useful here to note that one of the reasons we have our line custom made to our specifications is that we require the ability to quickly insert a splice in the material when the need arises, and our line is manufactured in a way that facilitates this.

PLEASE, If your line has a braid that is so tight you can barely get it to open, don't bother calling us for advice. We've tried lots of solutions. The electrical tape on the ends, melting the line and drawing it to a point, a "Shanty Sleever" tool that is typically used with smaller kite lines. It can't be spliced. If your line is made with KernMantle construction (ie. it has individual fibers running thorough the core of a braided sheath) it can't be spliced.

If you bought your line through TowMeUp.com though, you are in luck. All our line is super easy to splice. 

Costs and Sizing Information

We make an assortment of fids specifically for the lines that we carry. The most common fids are our # 5 fid which is designed to work with our 865# Leader Lines, and 1100# test Spectra Tow Line. The #6 fid is designed to work with our 1200#, 1400# and 1600# test Spectra Tow line. We make thousands of these fids a year for our own and customers use as well as for certain military applications. 

A #5 fid is approximately 4.0 inches long with a .152inch outside diameter and a 4/40 threaded opening in one end with a tapered ball point on the other end.
A #6 fid is approximately 4.0 inches long with a .178inch outside diameter and a 6/32 threaded opening in one end with a tapered ball point on the other end.

#5 or #6 fids sell individually for $6.95 each if purchased with a spool of line or a winch. Otherwise, they are only sold in minimum quantities of 5 fids. You can mix and match any size fid to fill your 5 pack. Any of these fids will include a shipping charge that includes the cost of Priority Mail at a minimum. We used to send them in an envelope, but we received well over half the fids back after we jammed up the automatic sorting machines at the post office. Apparently they can't read the "Hand Cancel Only" stamps.

It's possible to get other sized fids, but typically these are produced in limited quantities or have limited availability. They are typically a special production item, but we often have stock on hand since we tend to make up more than needed when we are set up to produce a run of a specific sized fid. If you need a custom size or color, we can easily produce it with reasonable minimum quantities. (Typically 50 pieces minimum unless we have over run stock on hand) The minimum quantity order from the fid below is 3, of which you can mix and match any size. Sizes we've made in the past, and may have on hand, but and can easily make again if we don't are:

.197" Outside Diameter x 8/32 thread

.250" Outside Diameter x 10/32 thread

.270" Outside Diameter x 12/24 thread

.300" Outside Diameter x.1/4x20 TPI thread

.375" Outside Diameter x 5/16x18 TPI thread

.500" Outside Diameter x 7/16 SAE thread

.750" Outside Diameter x 5/8 SAE thread

1.5" Outside Diameter x 1.4" x 24 TPI thread

10.0" Outside Diameter x 9.5" x 24 TPI thread

We can make any size fid up through about 10 inches in diameter, so please feel free to contact us for a price quote on special sizes.

Please call us for pricing on larger fids or quantity orders. We offer wholesale price breaks at 50 pieces.

Please note though that we only know exactly what size fid is the correct one for the line products that we carry in stock. Not all Spectra is easily spliceable. Samson, or Amsteel line is VERY DIFFICULT to splice, even when using our fids. There are a couple ways for you to get an appropriately sized fid. The quickest is to take a sample of your line to the hardware store and see what sized nut it is easiest to thread the line into securely. You want to choose the MINIMUM size that you can make work, since the splicing fid will need to go through the core to enable the splice to be completed. The best way to ensure we can get you the right size fid is to send us a short sample of the line you wish to splice and we will attempt to splice it and tell you the best fid to use, if it is even possible to splice.
