Installing Stainless Steel Press and Latch Cable Tensioners
These instructions provide step-by-step installation guidelines for installing the Press and Latch Cable Tensioner and Ender on straight runs. The tensioners are designed for 1x19 construction stainless steel cables of diameter 5/32” (4mm) or 1/8” (3.2mm). Each run of cable has a Cable Tensioner from one side and a Cable Ender (or Terminal) from the other side.
Wear protective ANSI approved safety glasses, working gloves and breathing mask at all times Press and Latch system only works with 1x19 strand construction cable
1) Cable cutter (recommended from Harbor Freight)
2) WD40 Spray Can (recommended from Harbor Freight)
2) 2 x 10mm wrenches
1) Release tool
2) Curved and Flat Washers
3) Cable Tensioner
4) Cable Ender
Important Note: All fittings (tensioners and enders) need to be oiled before attaching them to the posts. Do no skip that step or the cable won’t latch properly and will sag later. Spray WD40 inside the jaw latch mechanism.
1) Begin by inserting the provided washers (flat washer for square posts and curved washer for round posts) into the cable tensioner and ender then screw them into the posts using a 10mm wrench. Make sure they are tightened well
2) Press the cable into the terminal side first (for about 1 1/4” until it hits the back of the fitting) then make a sudden pull so the jaws latch on the cable. Watch this video for more details on how to sudden pull the cable https://youtu.be/ySnYLO_p2tg
3) Unscrew the turnbuckle of the tensioner to about 1 1/4” from each side, then mark your cable for the cut
4) Cut the cable using the cable cutter. You could release the cable from the cable ender (using the Release Tool) to measure and cut the remaining run of cables.
5) Release the tensioner turnbuckle. Press the cable into the tensioner latch mechanism (for about 1 1/4” until it hits the back of the fitting), then make a sudden pull so the jaws latch on the cable
6) Using two 10 mm wrenches (as shown in the below picture) assemble back the tensioner turnbuckle until the cable is tightened, then give the cable a small kick to latch it again. Then tighten the turnbuckle for the last time. Avoid twisting the cable by keeping the front part of the tensioner steady from rotating, the goal is to pull and tension the cable not twist it.
7) One common problem is cutting the cable too long. In this case, the cable tensioner doesn’t have enough threads left over to tighten the cable. Use the release tool to take the cable out, and return to step #3.
8) Another common problem is the cable keep pulling out from the cable fittings. In this case, the jaws inside don’t latch on the cable. Apply WD-40, and make sudden pulls to ensure the cable is latched.
9) Repeat the same for the rest of the cables of this run. The tensioners have a very high tensioning capability. The goal is to have equal tension force on all the cables. Over-tightening one cable will make the other cable loose. Be careful not to over tighten the cables. Make sure as well that the top rail tubing is properly installed and solid.
10) After making sure that all the cables are equally tensioned, tighten the two lock washers located at the two ends of the turnbuckles
Watch this video for demo how to release the cable from tensioners/terminals.
NOTE: A small amount of surface corrosion is not uncommon after some exposure to weather or salty conditions; we recommend using our passivation solution or a stainless steel polish to prevent surface corrosion; more information available on our Engineering Specs Page
