Form Fit Black PVC Foundation Sleeve 2 1/2" | 30" Long | Fits 2 1/2" Diameter Pole | Durable PVC Sleeve | Easy Installation

My husband is the flagpole guy and he thought this product was exactly what he needed.

Easy to use

Sleeve is fine, but no pin is provided to keep pole from shifting out of the bottom, or keeping the sleeve from climbing the pole.
