ABSTRACT:
A dowel sleeve has a tubular body with a mounting assembly at one end for releasable connection to a construction plate, and a leg support engagable at the other end for adjustable support. The construction plate has spaced non-circular holes. A first flange of the mounting assembly has a complementary profile, of smaller dimensions, to the non-circular holes, while a second flange has a similar profile, of larger dimensions, with its major-axis non-aligned with the major-axis of the first flange. The first flange is inserted through one of the non-circular holes, and the tubular body is rotated so the first and second flanges engage opposed faces of the construction plate.The leg support has a spigot engagable in the tubular body, the exterior of which is engaged by an abutment face. The effective length of the support leg is adjustable by selectively detaching one or more leg member segments, each provided with a disc-like base member.
