Protective Sleeves
Greatly reduces possibility of damage to plug due to debris and sharp objects in the pipe. The protective sleeve also protects plugs when the pipe is degraded. Works particularly well in coastal areas where oysters and barnacles are present. Features: • Extends plug life • Eliminates superficial cuts on plugs • Great for rental distributors & frequent users • Maintains back pressure ratings • Easy to install without special tools |

Remo®
The Remo® Remote Placement plug provides two advantages—it eliminates the need to enter confined spaces and speeds up the pipe plugging process. The system is safer and less expensive to use than conventional plugging methods because it requires no confined space equipment to simply block sewer flow. A lightweight aluminum pole system* or a standard 1Ľ" iron pipe** is used to place the Remo® plug in the sewer system. Remo® Plug Features: • Multi-size design to seal multiple pipe sizes • Can be locked at a 90? angle to seal openings in drop manholes • Can be used as a back plug for sewer tests • Adapters available to convert Muni-Ball® plugs into Remo® plugs Pole System Features: • Consists of 6' lightweight aluminum poles with push-button construction • Designed for plugs up to 30 lbs used in manhole depths of up to 20' • 1/6th the weight of iron pipe • Pole system requires Remo® pole adapter |
