They are suitable for use with 16 mm to 40 mm dowel bars in; „ Expansion joints „ Contraction joints „ Construction joints Advantages „ Made from strong galvanised steel - stainless steel available on order „ Suitable for 16 mm to 40 mm square dowels „ Provides lateral movement in joint of up to +/- 20 mm „ Fitted with compressible foam plug to accommodate bar expansion „ The system utilises integrated nailing plates – no need to drill edge forms Description The dowel sleeve is made from galvanised steel and incorporates compressible foam strips on the inside of each side of the cover that allows the dowelled concrete joint to move laterally by up to 20 mm in each direction. The range of sleeves are designed to accept standard 16 mm to 40 mm square dowels as designated by the engineer. Each dowel sleeve is fitted with a compressible foam plug which creates space between the end of the sleeve and the end of the dowel to accommodate for any thermal expansion of the metal dowel. The dowel sleeve is nailed to the edge forms. On removing the edge form the dowel sleeve remains in the concrete and is ready to accept the metal dowel.

The Flanged Dowel Box nailing plates should be nailed to the timber edge form at the height and spacing detailed by the Engineering drawings. Note: it may be necessary to support the end of the Flanged Dowel Box by using bar chairs or tie to reinforcing bars supported by bar chairs. After the concrete has hardened sufficiently (usually 24-36 hours), the edge forms can be removed and the appropriate metal dowel is then inserted into the dowel sleeve. October 2008
