The McAlpine USG3SS-SL-SC is a type of untrapped gully designed for use in plumbing systems. It features a 1½" horizontal outlet, a clamp ring, and a cover plate. The gully is made from high-quality stainless steel, which makes it durable and resistant to corrosion.

An untrapped gully is a plumbing fitting that is designed to collect wastewater and prevent it from flowing back into the building. It does not have a water seal or trap, which means that foul odours can escape from the drainage system. Untrapped gullies are typically used in outdoor or low-risk areas, such as garages or garden areas.

The clamp ring and cover plate provide a secure and hygienic seal for the gully, preventing any debris or dirt from entering the system. The cover plate also makes it easy to access the gully for cleaning and maintenance.

Overall, the McAlpine USG3SS-SL-SC is a reliable and high-quality option for anyone looking for an untrapped gully for their plumbing system. However, it's important to note that untrapped gullies should only be used in low-risk areas and should never be used indoors or in areas where foul odours could be a problem.
