Predl’s polypropylene steps are designed and manufactured to provide safe and secure vertical mobility inside a lined manhole structure. Staggered barbed ends create a secure connection with the inserts that are firmly embedded in the concrete riser through the wall liner. Bright red reflectors for greater visibility, molded finger grips for a firmer hold and a sure-footed tread design all contribute to achieving high safety standards in a confined, difficult working environment.
