• Grip designed to match rope twist direction (RHL).
• Special sized wires for ease of application.
• Galvanized steel and "C" coat construction.
• Color coded for ease of identification.
• Longer length to match Phillystran's high performance.
• Designed to develop the rated strength of the Phillystran products.

INSTALLATION PROCEDURE

1. Pretension the guy for easier Big Grip installation.
2. Insert heavy duty thimble into eye of Big Grip following "Installation Guidelines". Install Big Grip with thimble through attaching hardware. Begin the application of the grip at the cross-over marks (figure 1).
   
3. Wrap on the first leg (either leg) with two complete wraps. Align the cross-over marks, then wrap the sec- ond leg with two complete wraps, ending opposite the first leg.
4. Complete the application by wrapping both legs simultaneously (keeping legs opposite each other) or alternating legs half a wrap at a time (figure 2).
   
   NOTE: DO NOT completely wrap one leg at a time as is common with steel guy strand. (The second leg will not install properly due to HPTG-I rope distortion).
   
5. It may be necessary to split a leg to complete application of the grip. Be sure that all rod ends are snapped into place. A space or gap will be present between wraps (figure 3).
   
6. Trim back rope end to as short a length as is convenient and install end cap by applying silicone caulk or similar compound inside cap and pushing cap completely onto end of rope.
7. Secure black tie wrap around grip at rod ends to secure ends. Tie wrap should be positioned to within one (1) inch of rod ends of short leg.

INSTALLATION GUIDELINES

1. Strand Compatibility: Big Grip dead-ends should be used only on the size for which they are designed. They must have the same lay direction as the Phillystran to which they are applied. When ordering Big Grip dead-ends, make sure to specify the size on which it is to be used.
2. Big Grip dead-ends are precision devices that should be handled carefully. To prevent distortion and dam- age they should be stored in cartons until used and should be installed under the guidelines in this section.
3. During installation and at all times, care should be taken to avoid gouging or damaging the corrosion pre- ventive material of the Big Grip dead-ends or the jacketing on the Phillystran.
4. Big Grip dead-ends must not be used as tools, that is, come-alongs, pulling-in grips, etc.
5. Big Grip dead-ends may be removed and reapplied two times, if necessary, for the purpose of retensioning guys (without adjustable hardware).
6. If removal is necessary after a Big Grip dead-end has been installed for a period greater than three months, it must be replaced with a new Big Grip dead-end.
7. Big Grip dead-ends should not be applied with tools. They should be applied by hand. However, a screw- driver may be used as an aid in splitting the legs as shown in Figure 3.
8. Big Grip dead-ends should not be used on hardware which allows the strand to rotate or spin about its axis uncontrolled. Adjustable hardware, such as a turnbuckle, may be used as long as rotational movement of the strand is restricted.
9. Hardware used in conjunction with Big Grip dead-ends should have smooth contours, ample groove clearances, acceptable diameters and sufficient strength to minimize abrasion and fatigue of the loop area.
   A. Only heavy-duty type wire rope thimbles or solid (Hawser) type thimbles are recommended for use with Big Grip dead-ends.
   B. In order to prevent collapse of the thimble, either a solid (Hawser) type thimble, or a large pin inside the thimble or a smaller pin (such as a shackle pin) plus double extra strong weight pipe or equivalent is necessary.
10. Severe dead-end abrasion can result when high velocity winds load one side of a guyed structure causing the guy on the leeward side to slack off to a low tension. These winds cause a lightly loaded dead-end to cyclically load and unload against the connecting hardware and can ultimately result in damaging abra- sion. In order to keep the guys from going slack during high wind loading, we recommend that guy ten- sions be maintained at 10% of the guys published rated breaking strength. The articulated hardware illustrated will reduce the abrasion on the dead-end hardware interface when the guy is subjected to cyclic loading conditions.
