The Bessey Floor Spacers give you a simplified way to ensure you have correct expansion. Simply place around the edge of the floor and 'wind' the expansion until it is at the desired size. These floors spacers avoid the issues with wedges being stuck in the edge of the floor and also avoid spacers pushing through the plaster as they have an increased surface area. Each spacer also has a millimetre guide to ensure you have the exact expansion you desire. Available in a pack of 4.
