This cage is meant to replace the stock box on the F150 and is secured using the same screws as used to fasten the stock box.
Use as a bare cage or make some custom panels with styrene. Printed panels are also available
HERE
Note:
Due to the small diameter of the screw holes, some of the SLS powder may remain inside. This can be cleaned out with a small pick or pin prior to assembly.
**Pictures of installed cage show a previous version that did not include material that closed under the rear window and sides where stock box covered.
