The McAlpine BSWCLS 1½" Basket Strainer Waste with a 113mm Stainless Steel Flange, Spring-Loaded Plug, and Centre Pin Model is a type of plumbing fitting that is commonly used in kitchen sinks and other similar applications.

This particular model features a basket strainer waste with a 1½" diameter, which is designed to catch debris and prevent it from clogging the drain. The basket is removable, which makes it easy to clean and maintain.

The waste also features a 113mm stainless steel flange, which is used to secure the waste to the sink. Stainless steel is a durable and corrosion-resistant material, which makes it an excellent choice for plumbing fixtures.

The spring-loaded plug is used to control the flow of water through the waste. When the plug is pushed down, water is allowed to flow through the waste and into the drain. When the plug is lifted, the waste is sealed and water is prevented from flowing through.

Finally, the centre pin model refers to the design of the waste. The waste features a central pin that helps to keep the waste centered in the drain and prevents it from moving around.
