This review is for the yellow jacket 5138 and 5139 6 outlet heavy duty outlet strips. These strips are made by coleman...A trusted name in outdoor wiring. They are metal and well constructed. I particularly like the ability to seal off outlets that are not being used.'i would give these strips 5 stars if it wasn't for two irritating aspects attributable to either model. If you plan to just use these strips by just laying them down on a flat surface...Read no further...5 stars. But, if you plan to mount these on a vertical wall beware. No screws are included and good luck finding ones that will fit. You will need screws with a flat head and the head needs to be about 1/16thick. As well, the head needs to be no more than 1/4" in diameter. These screws are hard to find....Believe me, i've got hundreds of screws and i was barely able to find 8 screws for both of these strips.(you may be able to find other screws and file or grind out the heads though)..Another thing....No template iis included, so you have to make your own!
