Gaffer Tape

What this is about

Gaffer tape is the material the working day is held together with. Cables get taped down so nobody trips and the insurance stays valid, actors get floor marks, a flag gets an extra hinge, a rattling prop is silenced, a lamp keeps its gel. Its two defining properties are practical: the matte weave does not flare under a light, and the adhesive releases from a rented parquet floor when the day is over. That second point is what separates it from duct tape, and it is the reason location contracts survive. Buying cheap tape is a false economy paid in cleaning invoices.

A term only helps when everyone on set means the same thing by it — so what follows is how it is used, not a dictionary definition.

What runs differently here

Where this differs from the general case:

• Duct tape looks similar and leaves adhesive on floors, walls and cases — which is why locations ban it and gaffers refuse it.
• Colored rolls are used to code cables, mark actor positions and label departments on a shared truck.
• Gaffer tape is a consumable, so a shoot budgets rolls per day rather than treating them as a one-time purchase.

With TillyGen

Consumables appear in TillyGen's equipment list as their own line, so tape and sandbags are budgeted instead of bought in panic on day two.

Change one constraint and the consequences travel through the whole plan: affected shots are flagged, the call sheet is regenerated, and nobody keeps working from yesterday's version.
