Source 4WRD Will Not Fit on 2015 Fixture Body

The Source 4WRD retrofit will fit on most Source Four Fixture bodies. An exception to this is all Source Four bodies produced during 2015. This is due to a temporary change that was made to the metal on these bodies.

If you have a 2015 fixture body and are looking to install a Source 4WRD retrofit kit onto it, please give ETC a call so that we can get you the proper parts to make it fit.

How do you determine if you have a 2015 fixture?

We mark the yokes of all fixtures sold with a sticker denoting the month and year in which the fixture was produced:


  • The fixture in this image is from April of 2004.
