Figure 21 - Polytube Adapter
The polytube adapter option package does not include

tributor such as FOF Products, Inc., P. O. Box E, 1505
Racine Street, Delevan, WI 53115; ACME Engineering Co.,
P.O. Box 978, Muskogee, OK 74402; or any local green-
house supply distributor. Some local code authorities re-
quire the polytube material to be a listed material. Consult
code authority having jurisdiction and the polytube sup-
plier to determine the appropriate polytube material and
recommended methods of suspension.
