New I-Series Plugs!
Our new Cherne I-Series plugs are improved in several
ways. Smaller deflated diameter means easier access into small manhole openings.
New 3/4-inch eyebolts for added strength. And shorter length for more maneuverability.
And much more! All plugs include our patented Rupture Disc Technology, which gives
you a safer, longer-lasting product.
