Best AC Front Box for Camera Assistants: 4 Options Compared (2026)
The best AC front box for most camera assistants is one that mounts to a super clamp, keeps your most-used tools within arm's reach, and matches your cart and workload. If you want the short answer: the AC Frontbox Mini ($109) is the fastest, most compact pick for a 2nd AC; the AC Front Box XL ($129) gives you the most organisation; the AC Modular Front Box ($199) is best if you want to reconfigure your layout over time; and the Boom Box ($299) is the premium, heavy-duty choice. Below we compare all four so you can pick the right one for how you actually work on set.
What is an AC front box?
An AC front box is a rigid, tool-holding caddy that a camera assistant mounts to the front of a film cart, a stand, or a tripod leg using a super clamp. It keeps the small, constantly-grabbed items of the camera department, lens caps, filters, markers, batteries, tools, and focus rings, organised in one place and immediately accessible during a fast-paced shoot.
The name comes from where it lives: at the front of the cart, facing the AC, so nothing has to be dug out of a bag mid-take. A good front box turns a chaotic pile of accessories into a clean, glanceable layout, which saves time on every setup.
How do I choose the right front box?
Four things decide which front box fits you:
- Your role and kit size. A 2nd AC running a light kit wants something compact. A 1st AC or a rental-house cart wants maximum capacity and dividers.
- Your cart and mounting. Almost every front box mounts via a standard super clamp (Manfrotto or equivalent). Confirm you have a flat bar or pole to clamp to. Boxes here fit Inovativ, Magliner, Adicam, and SmallRig carts.
- Fixed vs modular layout. Dividers and removable inserts let you tailor the internal layout to the job. A modular box lets you add or swap parts later.
- Material and durability. PETG is light, tough, and the standard. Carbon-fibre reinforced options add stiffness and heat resistance for demanding sets.

AC Frontbox Mini: the compact pick
If you run a lean kit and want your cart to stay clean, the Mini is the one. It mounts to any super clamp and keeps lens caps, batteries, filters, and small accessories right where you need them. The standout is the removable insert: pull the whole tray in seconds for a quick equipment check, or swap layouts between setups without unpacking the box.
Compact PETG front box with a pull-out tray. Super-clamp mount and bolts included.
AC Front Box XL: the most organisation
When you need serious capacity without giving up cart mobility, the XL delivers. Three removable dividers let you build compartments around your exact kit, markers, tape, tools, and batteries all in their place. A large phone holder with a charge pass-through keeps your device powered through the day. It mounts on Inovativ, Magliner, Adicam, SmallRig, and most standard carts.
Large rigid PETG box, 3 removable dividers, phone charge holder. Fits most film carts.
AC Modular Front Box: build it your way
The Modular is for ACs who want a box that changes with them. Printed in parts, it supports future configurations, multiple tool-holder sizes, a can holder, focus-ring storage, and a side loader for a drink or long tools. Choose standard PETG, or upgrade to ABS-CF (carbon-fibre reinforced ABS) for extra stiffness and heat resistance up to 95C.

Boom Box: the premium build
The Boom Box is the heavy-duty, engineering-grade option. Its main shell is durable, lightweight ABS glass fibre, with front and side bars in nylon carbon fibre for hanging power tools, hooks, and carabiners. It mounts horizontally or vertically to poles, stands, or boom baskets, and includes a reconfigurable white insert. If you want the toughest box on the cart, this is it.

PETG vs ABS-CF vs carbon fibre: which material?
Most front boxes here are printed in PETG, which is light, impact-resistant, and reliable for daily on-set use. If you work in hot environments (a box left in a vehicle or in direct sun) or you want maximum rigidity, an ABS-CF (carbon-fibre reinforced ABS) option adds stiffness and heat deflection resistance up to around 95C, plus a premium textured finish. The Boom Box goes further again with an ABS glass-fibre shell and nylon carbon-fibre bars for hanging heavier tools. For most ACs, PETG is plenty. Choose a carbon-fibre option if heat or extra stiffness matters for your work.
Frequently asked questions
What is an AC front box used for?
An AC front box holds a camera assistant's most-used tools, lens caps, filters, batteries, markers, and focus rings, in one organised caddy mounted to the front of a film cart or stand. It keeps everything within arm's reach so nothing has to be dug out of a bag during a take.
How does a front box attach to a film cart?
Front boxes mount using a standard super clamp (Manfrotto or equivalent) with the included bolts. The clamp grips a flat bar or pole on your cart, stand, or tripod. The boxes in this guide fit Inovativ, Magliner, Adicam, SmallRig, and most standard film carts.
Which front box is best for a 2nd AC?
For a 2nd AC running a lighter kit, the compact AC Frontbox Mini ($109) is usually the best fit. It keeps small accessories accessible without taking up much room on the cart, and its removable tray makes equipment checks fast.
What is the difference between PETG and carbon-fibre front boxes?
PETG is a light, tough plastic that suits most on-set use. Carbon-fibre reinforced options (ABS-CF) add stiffness and heat resistance up to around 95C, which helps if the box lives in a hot vehicle or in direct sun. For most camera assistants, PETG is more than strong enough.
Do these front boxes come with the super clamp?
The mounting bolts are included, but the super clamp itself is usually sold separately. Check each product page: it lists exactly what is included and which bolts you need for your cart.
