I'm guessing I'm not the only one who cuts a second hole in the slide plugs to use them as a handy was to tap into a line and create a quick branch line. Has anyone ever seen slide plugs that have no polarity? I wonder why any light sets are made still with old school plugs that have no polarity. When I buy slide plugs I take all the male plugs and zap them with my Magnamatic grinder. I save my old wheels that are not good for blades anymore but work perfect for slide plugs. I think Sival had the best deal on plugs unless you need 2000 and then it was Litesource. LiteSource is good on minimum orders for most things so I'm surprised they require you to buy so many. Has anyone actually purchase 2000 plugs before?
