Product description: Speed Sleeves are used with friction cut round dowels to completely eliminate the need for drilling formwork and greasing dowels. Speed Sleeves contribute to a huge reduction of vertical movement at joints, reduce potential joint damage and are quick and very easy in application. Speed Sleeves are perfect for use in industrial sized ground slabs with multiple joints. They are available in 16mm, 20mm, 24mm and 33mm standard sizes. Speed Sleeves nail to wooden form boards with the use of an optional nailing plate (sold separately) or can be used in conjunction with existing / epoxied dowels before subsequent concrete pours.
