S & K Ground Sleeve, Fits Tri-Tel Pole

I used a red-tile chimney flue section that was about 16 inches tall with an 8-inch opening for my buried base.. I dug the hole so the plastic sleeve would fit flush to the flue tile and set the entire base about 1 inch below the surface of the ground (to avoid the lawn mower blades). I bought a sack of concrete with gravel for about $6 and used it to fill the hole with the sleeve in place and filled the inside of the tile. I put a Walmart sack in the bottom of the sleeve so it would not allow wet concrete inside of it and also put three Walmart sacks inside of my tri-pole to keep the wet concrete out of it while the mix was setting up. I slipped the tri-pole into the sleeve, used a level to ensure the pole was straight at all three sides and then watered the concrete mix. When it had set up, I noticed there was just a slight lean and I used a plastic toilet shim to set it straight on one of those three sides It made a nice tight fit. The pole is straight, the cost was minimal and I can easily remove the birdhouse with the pole for cleaning or maintenance. — Brett from TN
