The insert has tapered upper edge projections and is rotatable for vertical engagement with projections formed on the inner edges of the brackets. A cylindrical support ring may be provided to rest on notches formed on the inner edges of the brackets, and when fully assembled the insert may rest on the support ring for full annular support by the ring. Locking washers may be provided to prevent disengagement of the projections on the insert and brackets.
