Negate Nag <br /> Anchors, inc. <br /> INSTALLATION NU-CONCEPT ANCHOR CLASS 3&4 <br /> Patent Pending <br /> j The Nu-Concept Anchor combines a patented elongated hole in the tension head with <br /> a stabilizing and compaction cap. When combined with a grade 5 bolt, the anchor will <br /> rotate in all directions allowing adjustment to uneven terrain. Under load conditions the <br /> cap, rotates down ward in the direction of the pull, causing a double compaction of the <br /> soil and laterally restricts movement of anchor through the soil. <br /> I , Attach stabilizer/compaction cap to the tension head of the anchor. This is done by sliding <br /> the cap over the top of the tension head, aligning 9/32" holes in cap with 1/4" elongated <br /> hole in tension head. Insert 1/4"x 2-1/4", grade 5 bolt (included). Hand tighten. Cap must <br /> be installed at anytime prior to ground contact. Figure A Figure B <br /> See Cap Figure A and Tension Head Figure B. (TOP) <br /> ❑ ❑ <br /> 0 <br /> Class 3 - 4430 NU 3/4 (BOTTOM) <br /> Class 4 - 4636 NU 7/8 11 The Drive Machine is started and the <br /> anchor is turned into the ground to a point <br /> where the bottom of the tension head is at <br /> or slightly below ground level. This insures <br /> Stabilizer/ odmpacting maximum soil compression by the cap. <br /> aezAMINE. Figure C See Figure C. Engineered to allow ground <br /> anchor to be installed at a slight back angle <br /> of 15° <br /> Class 3 - 4430 NU 3/4 <br /> Class 4 - 4636 NU 7/8 <br /> 110 <br /> Stabilizer/Compacting <br /> Head <br /> Anchor is pre-loaded. Pre-load causes <br /> the cap to rotate downward in the Figure D <br /> direction of pull, further compacting the <br /> soil and presenting a larger surface <br /> area, resisting both horizontal and imo <br /> vertical movement. See Figure D. <br /> When used with rigid support tubes, 110 <br /> rather than strap systems, pre-loading is <br /> not required. <br /> Note; A special adapter is available to insure against tension head and bolt damage.
