  • "I've been waiting for someone to develop this product for at least 5 years now - beyond pleased with how well this tool worked with my router. Communication from seller was outstanding, and the attachment exceeded my expectations. Thank you so much for making this product which enabled me to finally put a proper weather seal on the front door of our 116 year old home."

    —mikies450r (Plano Frost Replacement Latch)

    —daverogotzke (Corner Grooving Router Base For Weather Sealing)

  • "Upfront communication was good, with prompt shipping & notification. Hinges fit well & are made stronger than the OEM hinges. Excellent transaction! I couldn’t find the OEM hinges anywhere, glad I bought these, better quality than OEM hinges!"

    —tommystetson (Frabill Magnum Bait Station Latch Assembly)

  • "Awesome seller. Great communication. We weren't quite sure which base my Porter-Cable trim router would use, so he did a little research, came back with a recommendation and said "If it doesn't work, I'll find one that will." In short -- fit like a glove and works perfectly. HIGHLY recommended."
