3-1/2" Max. O.D. PVC Insulation Tee Fitting Cover By TechLite Black Proto 8 118V. You can cut out tee size on middle to what you need or have comming out for clean looking fit. Check out my other stores on Ebay, one of the largest inventories of "Creatology" and "Celebrate It" products from Michaels Stores more 1950's "pinup/model" pictures and Negatives. Bonanza has both my ebay stores combined into my Bonanza Booth, "DiscountCrafts4U", except the items I have listed in the "other" category on ebay that are not listed on Bonanza. Remember you can make an offer on any of my items on Bonanza by adding the item to your cart and then open the cart and click on the "make an offer" link. Be sure to check out all the freebies I have listed here on Bonanza too. My other 2 stores are: http://stores.ebay.com/Stargate-Cool-Stuff?_rdc=1 http://stores.ebay.com/Debbie-Dabbles?_rdc=1 You will not find better deals for the price anywhere. I combine ship on both stores to save you money. I have great feedback - fast ship - lots of other great stuff to check out.
