Gleco Trap System® 3.5-Gallon HV Refill

The 3.5-Gallon Gleco Trap^® HV Refill features a newly engineered, air-tight lid with threaded inlet and outlet extensions that reserve an air pocket inside. When the trap is full, simply remove the air-release plug to drain inlet and outlet plumbing into the bucket before disconnecting. Patented design prevents the mess and contamination that occurs with removal of traditional plaster traps. 11"H.
