Check out the videos and find more information (including installation instructions) at Ailuros Workshop on Facebook: https://www.etsy.com/shop/AilurosWorkshop The ONE-PIECE POLE ($225) fits ceiling heights up to 97-3/4". It can be made shorter to accommodate any height. TO ORDER: SEND US THE EXACT HEIGHT OF YOUR CEILING and we will make the pole specifically to fit your space, with 5-1/2" of adjustment as measurement tolerance and also to allow the Pole to be moved to other spaces. EXTENSIONS can be made to fit a higher ceiling. For instance, a 106" high ceiling would require a stock pole and a 10" extension. The total cost would be $275. INSTALLATION requires only a small hole in the ceiling and tightening the threaded rod with the included 7/16" wrench. Instructions and hardware are also included. A rubberized base is available for installation on CARPET. ***We have a new installation option that requires no drilling. It involves a 1/4" plywood plate affixed to the alignment block that has double-sided tape for adhesion to the ceiling. A separate listing in our items will be created with more info.*** The Cat Pole has been tested for many years by dozens of cats and their humans. It's fun (some cats climb over 50 times a day). It's durable (it should last a lifetime). It's simple to install (it can take less than 5 minutes). Almost no glue is used in the fabrication—mechanical fasteners hold everything together. The pole is composed almost entirely of natural 3/8" sisal rope, solid pine board and countersunk black oxide wood screws. The sisal rope is pulled to high tension when wrapped around the pole. (Sisal rope is a natural fiber rope that does not have any oils or chemicals and is safe for use with pets). The Cat Pole will be shipped UPS Ground. It will be packed in two walls of corrugated cardboard. If also ordering a Cat Pole extension, the extension will be shipped separately. Installation ($75) and hand delivery ($TBD) in New York City is available. Email questions to James at [email protected].
