+
+Optionally, dab some low-strength thread locker into the threads of the t-nuts. Be careful not to get it on your printed parts as it can degrade the plastic.

2 |  |
+{: class="hardwaretable"}
+
+Position the new extrusion between the top and bottom rear horizontal extrusions of the printer, and with the top of the new extrusion between the corner bracket. Make sure the new extrusion's t-nuts are at the top.
+
+Thread the two M5x8 bolts through the corner extrusion and into the new extrusion's t-nuts.
+
+Tighten the bolts attaching the corner brackets to the new extrusion, making sure the brackets are flush to the front and back of the extrusion, or at least centered on its groove.
+
+#### Position the extrusion
+
+Use a tape measure or other measuring device to make sure both the top and the bottom of the new extrusion are centered. Once satisfied, tighten the bolts attaching the corner brackets to the rear top horizontal extrusion.
