Not really. Plastic anchor sleeves are mass produced in standard sizes and are not feasible to be custom made with custom diameters or lengths. The tooling/molds to create a custom size are expensive and have long lead times to such a degree that the manufacturers of the sleeves are unwilling to pursue custom tooling. If a longer sleeve is required to enhance adjustability, or other strength/installation concerns, a welded pipe sleeve should be considered that can be custom made per an engineer’s specifications.
