25 Grip and Electric Terms Everyone on a Film Set Should Know

You will inevitably need something from the grips or electric department if you spend enough time on set. They will often be willing to help (if you ask politely and at a good time), but it always helps if you know what the piece of equipment you need is actually called. Here’s twenty-five grip and electric terms that will get you started.

Apple Box – A wooden box that can be used for almost anything. Comes in various sizes and is commonly used as steps, seats and to raise props, dressing or actors.

Barndoors – Folding doors that are attached to the front of lamps so they can be opened and closed to control the output of light.

Bazooka – A camera mount similar to a tripod but only has one center shaft that raises the camera up and down.

Beef – The output of light.

Best Boy – The second in command of the grip or electrics department. They often do most of their work off set in the truck as they plan for the future shooting days.

Black wrap – Black aluminum foil that is used to cover light leaks or shaped into flaps to cut the light.

C-stand – An extremely versatile metal stand used for holding lights, floppys, cutters and anything else you need stabilized.

Dance Floor – When it’s impossible to lay a track in the set or the camera move is more complex than a simple push in, the grips will lay smooth timber or plastic sheets down onto the ground to crate a perfectly level floor. The dolly can then be pushed in any direction with minimal bumps and vibrations to the camera.

Diffusion – A white material used to soften the light source.

Dimmer – A device used to control the power of the lamp.

Dingle – A piece of cut-off foliage to provide the lighting effect of a tree shadow on the subject.

Dolly – A heavy piece of equipment that the camera can be mounted onto to give a smooth moving shot. The dolly slides along a track that looks just like a train track. This is extremely heavy; avoid being too close to the grips when they are looking for a hand carrying this up the stairs.

Duvetyne – A thick, black cloth used for blacking out windows, and covering equipment and crewmembers when they are in reflections.

Floppy – Square or rectangular frames with black material used to control the light. They can be used to cut the light off a certain subject or to black out an area for the director’s monitor.

Gaffer – The head of the electric department.

Gel – A transparent colored filter that is applied to the front of a light to manipulate the color output.

House Power – Using the location’s power as opposed to power supplied by the electrics generator. Always good to check with the electrics department that it’s okay to plug into house power.

Key Grip – The head of the grip department.

Key Light – The main source of light on a subject.

Lamp – Just another word for a light. The electric department tries to be all fancy and such.

Scrim – A type of material similar to diffusion to manipulate the intensity of the light source. Typically scrims are quite large, either 10’x10’ or 20’x20’ and used to diffuse the harsh sunlight when shooting exteriors.

Shot bag – A heavy bag full of lead shot used to weigh down stands. Looks like a sand bag.

Stinger – A single extension power cord left ‘hot’ by the electrics for occasional use.

Track – Steel or aluminum track that the dolly glides along to create smooth camera movements. The track is laid level by the grips across all types of terrain using apple boxes and wedges.

Wedge – Small timber triangles used to level the dolly track.
