Net Pole Detail
1. The net poles are 4" diameter, 7/32" wall, 6061-T6
aluminum tube and stand 23'-8" (7.22m) tall in their 3'-6"
ground sleeves. The poles roll inward offsetting the net 1
meter at ground level. Vertically swinging net arms at each
pole position hold the net in place and allow the net to
envelop an errant hammer then drop back into position.
5/16" net rope swivel pulleys with eyebolts attach to the top
of each net pole to facilitate the raising and lowering of the
net.
2. The 14' 3 1/4" (4.35m) wide by 26'-3" (8m) tall aluminum
doors are constructed of the same heavy wall tubing as the
net poles. All corner joints are securely welded and cross
braced. Each door comes in four sections and is easily
assembled at the site. Sections are securely bolted
together utilizing 28" long, 1/4" wall, inner sleeve tubes.
The outermost vertical frame member has been replaced
with a steel cable to hold the door net in position. This
design minimizes the frame structure a hammer can hit at
its most vulnerable position.
3. The doors pivot on two 4" diameter, 8 gauge, galvanized
steel poles set vertically in 3'-6" ground sleeves. Each pole
utilizes two heavy duty hinges with bronze thrust bearings
and 1 1/4" stainless steel hinge pins. The positions of these
hinges can be adjusted to compensate for any settling of the
concrete door runways. Doors swing from the closed to
fully open position.
4. The net is fully supported between the doors and the
first net poles by 1 5/16" galvanized steel tubes. There is
also a net support tube between the two rear most net
poles, above the rear entrance. The rest of the net hangs
free with a heavy rope reinforcement to minimize sag. The
nets are constructed of 749 lb. test, #84 knotted, weather
treated nylon. The cage doors are double netted.
NOTE: Ground Sleeves are sold separately.
