An ARRI 435 production carrying 400-foot magazines runs through a lot of mags in a shoot day — typically three Mag 120 and three Mag 120 S in rotation, swapped between camera and reload bag. This case carries all six magazines in one shell, with CNC-cut foam cradling each mag in its working orientation so loaded film doesn't shift in transit.The CNC-cut foam interior has six dedicated cutouts (three for the Mag 120, three for the Mag 120 S), sized to the exact mag body with cutouts around the take-up reel hub and the mount interface. Each cutout holds the mag with the loading door facing up for fast access during reload, and the foam is profiled so loaded mags don't bear weight on the loading door during transit.Shell is ATA 300 Category 1 with recessed ball-corner latches, pressure-equalization valve (critical for film magazines crossing altitude), and reinforced soft-grip handles on both ends for two-person lifts (a loaded case is heavy).Built in our North Hollywood workshop. Lead time 14–21 business days. For variants with different mag count or for ARRI 416 200-foot magazines, call 818-767-3030.

Will this fit my setup?

Tell us what you’re protecting and everything that travels with it. We check it against this build’s foam layout and reply with either a confirmation or the change we’d make. No obligation, and it goes to the people who cut the foam.

We reply with a real answer, usually same business day.

My setup is different

Different body, extra accessories, an accessory that has to stay mounted, or dimensions that don’t exist yet. We modify an existing design or engineer a new one.

I need several

Repeatable foam layouts, consistent hardware, replacement foam and reorders against the same drawing. Standard practice for rental houses and studio fleets.
