9” Diameter opening x 12” Length
The MB-9 is light weight and partly nestable which can save the
customer money in freight and shipping/handling charges. When
setting in concrete our design does not require a ring. The MB-9
has a wide variety of applications including water spigot cover and
water sprinkler shut-off valve. The MB-9’s unique design makes
it extremely strong as you can see by the photo to the left.
Our structural foam molding process allows our parts to have a cell-
ular foamed core surrounded by integral skins. The process gives
our product high strength-to-weight ratio making it have greater
rigidity than solid parts of the same material and of equal weight.
