Web-Shooters are a pair of wrist-mounted mechanical devices developed and used by Spider-Man to project Synthetic Webbing. The trigger rests high in the palm and requires a double tap from the middle two fingers to activate.

Spider-Man must steadily replenish his webbing supply, reloading his web-shooters with small cartridges of web fluid. Originally he carried his extra cartridges in a utility belt worn under his costume. Later on, he equips the web-shooters with a bracelet-like carousel that automatically rotates a new cartridge into position as he empties them.
