    • Quick Facts:

      • Available in four (4) Inner Diameter Sizes; 24", 26", 28" or 32" ID
      • Each kit contains segments to create Three (3) rings of diminishing outer diameter (OD) but the same inner diameter (ID) to 'smooth the transition' between the height of the pavement and the steel man hole casting
      Made in USA

      Please Note: Minor cracking of the material during transit is normal and does not affect performance or durability. Once properly aligned and applied with heat, the material will fuse seamlessly to the surface, and any visible cracks will disappear.

    PREMARK® Thermoplastic Manhole Protection Rings

    PREMARK® Thermoplastic Manhole Protection Rings are designed to create a smoother transition around raised manhole covers, helping reduce impact from daily traffic, snowplows, and maintenance vehicles. Made from durable 125 mil non-beaded preformed thermoplastic, these rings provide a tough, heat-applied ramp around manhole frames where grade changes can create a rough ride or potential damage point.

    Each kit includes segments to make three separate rings with the same inside diameter and different outside diameters, allowing crews to adjust the height difference from approximately 1/8" to 3/8" by applying one, two, or three rings as needed. The subtle incline helps traffic pass more smoothly over the manhole area while providing a clean, professional-looking finish on asphalt surfaces.

    • Helps smooth raised manhole transitions for daily traffic, plow trucks, and maintenance vehicles
    • Durable 125 mil PREMARK® preformed thermoplastic construction
    • Stackable 3-ring kit allows adjustment from approximately 1/8" to 3/8"
    • Heat-applied installation using an approved propane heat torch
    • No minimum air or road temperature required for application
    • Available in black or gray to blend with surrounding pavement
    • Ideal for municipalities, paving contractors, and roadway maintenance crews

    PREMARK® Manhole Protection Rings are a practical solution for reducing the bump around raised utility castings without grinding, milling, or major pavement repair. Simply prepare the surface, position the ring, and heat the thermoplastic until it bonds to the pavement.
