Pull out installed around 2012

Hello, Joe. Looks like a type of spacer for your track. We don't sell this exact style, but we do sell a double different bracket sizes that you may be able to use as an alternative. See our 32-339 and 32-352B to begin with. Using these would require drilling new holes, and the best match will depend entirely on what kind of depth you need, but I think these are a great place to start.
