I’ve searched high and low for these parallel gliders to stock them in the TPK Supplies Shop! It was almost impossible to get a hold of them in 2020 because Alvin, the manufacturer, went out of business. In 2021, another company acquired the rights to manufacture the parallel glider (/”rolling ruler”). I’m pleased to say that the new Alvin parallel gliders are identical to the original parallel glider that I fell in love with in 2014. (I’m still using the same one!)
A parallel glider is a bit of an investment, but it’s a tool you’ll return to again and again, and it lasts for years. If you’ve been using a parallel glider with a plastic base, you’ll be amazed at what an upgrade this aluminum-based beauty can do!
