The float handle is attached with screws or adhesive, and can be made of plastic or wood.
The handle may be moulded into the body if it’s a plastic float.
Base plate
The base plate can be made of aluminium, plastic, wood, magnesium or stainless steel. It’s attached to the handle on one side, and the backing layer on the other. Most plastic floats are manufactured with the handle moulded into the body.
Backing layer
The backing layer on the face of the float varies in texture and can be made of sponge, rubber, plastic, wood or magnesium. Some sponge floats have replaceable backing layers.
