WallMax® Round Squared frames are round structures with an inner, squared packing space that accommodates modules of the WMR series.
Multiple dimensions of packing space are offered to allow for maximum variety in module combination and maximum adaptability.
Sealing of passages is obtained through tightening of the bolts on the flange, with no need for use of an expander or retainer plates.
WRS frames can be completed and mounted with an additional external sleeve, which is sold separately as an accessory.
