The Feherguard 1.5 inch Yellow Threaded Plug is a smart, reliable solution for winterizing above-ground pool returns and plumbing lines. Designed with internal threading, this plug allows pool owners to attach an empty plastic bottle (such as a chemical bottle) to create a DIY ice expansion buffer, similar to a Gizmo.

When installed in the pool return, the attached bottle compresses as ice forms, helping to relieve pressure caused by freezing water. This reduces the risk of cracked fittings, damaged returns, and wall stress during harsh winter conditions.

Manufactured in Canada, this durable winter plug is a must-have for proper pool closing and long-term protection of your above-ground pool structure.
