NOTE: 

For the final assembly on all the elements, it is best to perform the next steps on the ground or long flat surface. 

This will aid during final adjustment of the ELEMENT OVER HEAD SUPPORT. 

The ELEMENT HALVES are symmetrical 

on both sides. Do each of the following steps on both sides of the ELEMENT. 
 
STEP 15: 

 

Slide ELEMENT SECTION #2 onto ELEMENT CENTER SPLICE or INSULATOR.   

 
STEP 16: 

 

Slide ELEMENT SECTION #1 onto ELEMENT SECTION #2. Insert hardware and tighten locknut. Attach VERTI-

CAL RISER ASSEMBLY.  For the driven element you need to add (4) CLAMP BLK, 3/8 (HAIRPIN) (M2AMC0261) and 
hardware. See drawings for hardware call out for the different elements. 

 

 
STEP 17: 

 

Insert ELEMENT SECTION #3 into the end of ELEMENT SECTION #1. Insert and tighten hardware.    

 

STEP 18: 

 

Insert the ELEMENT SECTION #6 of the COIL ASSEMBLY previous assembled in STEPS 1-10 into ELEMENT 

SECTION #3. Insert and tighten hardware.  

 
STEP 19: 

 

Insert ELEMENT SECTION #5 into the end of ELEMENT SECTION #4. Insert and tighten hardware.    

STEP 20: 

 

To be able to adjust the ELEMENT TIP, a COMPRESSION CLAMP is used. First thread on the hex nut to capture 

the screw in the CLAMP. Then slide the COMPRESSION CLAMP such the screw is lined up with the hole in ELEMENT 
SECTION #5. Use the DIMENSION SHEET and set the proper exposed length of the 1/2” ELEMENT TIP for the appropri-
ate element, then mark the element assembly to avoid confusion later. See GENERIC COMPRESSION CLAMP DETAIL 
page for more detail. 
 

STEP 21: 

 

Tensioning the element over head guys: 

See the LOCK BLOCK AND KNOT DETAIL page. Familiarize your self 

with knots at the top of VERTICAL RISER, bend the thimbles open and insert them into the holes on the top plate of the 
VERTICAL RISER, then bend them back to there original shape. Follow the knot diagram and tie the upper section of 
rope, leave no more than 3” of excess rope and finalize by taping the short tail of rope down to the main portion of rope. 
Thread the opposite end of the rope through the ELEMENT OVERHEAD SUPPORT (M2APL0212) (See the LOCK 
BLOCK AND KNOT DETAIL page) and tension the rope so the element is in a level or neutral position. It is always best to 
have the element in a level or neutral position or with a slight sag downward. Over tensioning can lead to a bowed ele-
ment. This finalizes the element construction.
