GENERAL STEP-BY-STEP GUILDLINES FOR
INSTALLING A PORTER WALL–MOUNTED BACKSTOP
On a Model 219 up-fold unit, it will be necessary to temporarily chain or rope off the lower extensions to the
top extension in order to hold them in place. On the Model 220 side fold units, 3/16” x 1-1/4” flats placed
between the top and bottom extension tubes will aid in holding the lower extensions in place, but it is still
necessary to temporarily chain or tie the lower extensions in place. Again, measure the distance of the sup-
port tubes at wall to the finished floor, ensuring the locations are correct to yield a 10’-0” goal height (or 8’
goal height if so specified).
15. Utilizing a block and tackle system or, preferably a lift, hoist the backboard in place, and secure to the
extensions utilizing the hardware specified on your project specific drawings.
16. Drop a plumb bob (or laser mark) from the face of bank to the floor, and adjust the extension to the
courtlines, typically 15’-0” to the free-throw line, and 4’-0” to the base line, but not in all cases. Secure
the setscrews on the extensions, ensuring the backboard is plumb both vertically and horizontally to the
court.
17. Mount the goal, and check the elevation for 10’-0” A.F.F. The height can be adjusted by sliding the
chain support on the top extension forward or back for nominal adjustment. For greater adjustment,
chain links can be changed in the terminating bolt of the half-clamp. It will now be necessary to re-
plumb the backboard.
18. Tap the clamps securing the flats in place for tension, and tighten all flat-clamps. After all adjustments
have been made, secure the telescoping extensions with the rivets specified by drilling through the pilot
hole on each extension, and driving the rivet through the holes. Repeat this procedure at the half-clamp
securing the chain.
19. Check all hardware connections for tightness.
20. On Model 219 fold-up units, follow the project specific installation print for mounting the winch and pul-
leys. See Detail “G” for cable tie-off.
21. On Model 220 side fold units, follow the project specific installation print for installing the telescoping
diagonal brace tube. Refer to Detail “H”.
22. Operate the folding units a minimum of three times to ensure functionality, and that all final adjustments
have been made.
