You may be using a poly plug but not The Poly Plug by Pest Boys. If you're using a plastic or rubber plug, you are using some of the most expensive plugs you can buy just to cover them up with patching materials. The Poly Plug by Pest Boys is the most economical material which is a foam plug that is significantly cheaper to purchase, faster, and much easier to install than the competitions products. Most of the people who view this product will think the time you will save is due to the plugs. But the real time saver which will boost your productivity is the T-Handle Tool. It takes a tech about 7-12 seconds to set most other types of plugs to a good depth to patch. But, if you use the T-Handle Tool with all types of plugs, it only takes 1-2 seconds per hole. Now for a single hole plug, that doesn't sound like much. But when you're doing 300 hole plugs per building, that's a huge amount of time. The time saved for buildings with 300 holes to plug and patch will be as much as 4 1/2 labor hours. That's a lot of bending over and back ache time.
