Grease Trap Riser Extension

Extension Risers for 15 to 50 GPM grease interceptors, as an extension for below ground installations.  With their modular design, risers can be stacked on top of the interceptor to adjust the finish height of the cover relative to the floor. They can be cut to height on site using common tools and offer up to 6" (max.) of height adjustment per riser. We recommend not exceeding 3 risers (18" max.) per installation to maintain reliable access to internal components of the interceptor requiring regular maintenance. Installation instructions provided.  See chart below for compatibility.

• Injection molded in engineered thermoplastic, that will not corrode, chip or peel, even under the most severe applications
• Each riser provides 1.5” to 6” of height adjustment (cut to suit)
• Stack up to three (3) sets of risers per installation to maintain access
• Supplied with stainless steel screws for installation
• Molded guide lines included to assist with cutting accuracy
• Cut-to-length on site for installation flexibility and flush to grade installation
