4.  Mark screw positions for front and rear 
 
connectors and pre-drill pilot holes about ¼" deep 
 
using a 
1
16
" drill bit. TIP: Wrap masking 
 
tape ¼" from drill tip to set drilling depth. 
 
Use care not to drill through tabletop.
5.   Fasten front connectors to front edge of board
 
as shown in Figure 2 using ¾" screws. Fasten 
 
screws half way. Do not fully tighten.
6.   Assemble right rear connector as shown in Figure 3 
 
and fasten to board. Select screw length based upon  
 
board thickness.* Fasten screws securely. 
  *For board thicknesses of 5/8" or less:
 
If your board is 
5
8
" thick or less please use the  
 
5

" screws in place of the ¾" screws as shown in 
 
Figures 3 and 4. Do  not use ¾" screws included 
 
with hardware kit since they might break through 
 
bottom of board.  
7.  Assemble left rear connector as shown in  
 
Figure 4 and fasten to board. Fasten screws 
 
securely. Pulleys are designed to be tight fitting 
 
and do not spin freely.
8.  Place straightedge in center of drawing board  
 
parallel to front edge as shown in Figure 5.  
9.  Loop upper wires around pulleys in rear wire 
 
connectors making sure that spring is centered.  
10. Thread lower left and lower right wires through 
 
front wire connectors. Wire should pass  
 
between connector and board as shown in 
 
Figure 6. 
11.  With spring still centered at top, pull slack out 
 
of wire passing through lower left connector  
 
and wrap wire around mounting screw. Fasten 
 
screw securely.
12. Pull slack out of wire passing through lower right 
 
connector until spring at top is stretched to about 
 
2½" in length. Wrap wire around mounting screw 
 
and fasten screw securely. Use care to set spring 
 
tension as directed for best performance.
13. Excess wire can be trimmed off leaving 
 
several inches for future adjustment.
