LTTP2 — an Update to a Classic Light Tension Tie By Paul McEntee t would give you an incomplete idea of the new LTTP2 light tension tie if we didn’t first discuss the original LTT series. The LTT20 tension tie first appeared in our 1987 Connectors for Wood Construction catalog as a post-pour, wood-to-concrete connector. The LTT20 installed with nails only, but we realized we could add holes for bolts, so the LTT20B gave the customer the option to use either nails or bolts. Around the same time, we created the narrower LTT19 for installation on 2x joists or purlins. For more than 30 years, the LTT19 and LTT20B quietly anchored walls to roof diaphragms or shearwall posts to foundations.

We manufacture the LTT in a threestep process — make the strap, make the load transfer plate, and then press the two together. Over the years, we tried different options for creating a one-piece design, but it was difficult keeping new designs as low profile as the current LTT was. Then, a few years ago, one of our product managers was visiting one of our German offices and spotted an angle connector on display in the lobby. The AKR angle gave us some inspiration for a new version of the LTT manufactured in one piece. The nail pattern was not quite right for installation on an I-joist or a single 2x joist, but the seat shape was relatively low profile and had the stiffness we needed. While adapting the European design to meet North American requirements, we also developed an extrusion on the anchor hole that improves load transfer in the holdown seat.
