Abstract
A dowel placement system including a fastener configured to be engageable with a form, and a radially compressible bushing coupled to the fastener and defining an adjustable outer diameter. The system further includes an elongate dowel sleeve having opposed proximal and distal end portions, and an axial opening having an inner diameter and extending into the dowel sleeve from the proximal end portion to the distal end portion. The bushing is insertable within the axial opening of the dowel sleeve, and the bushing and dowel sleeve are configured such that insertion of the bushing within the dowel sleeve causes the outer diameter of the bushing to compress and conform to the inner diameter of the dowel sleeve and to create a friction force between the bushing and the dowel sleeve to mitigate movement of the dowel sleeve relative to the bushing during formation of the concrete structure.
