Drill Chair Quadruple Shotgun Hallway Trap Zep's Test
Sing is... dead. It's all my fault. I'm sorry.
— Tapp, mourning the death of Detective Sing

The Quadruple Shotgun Hallway Trap is a trap from the Saw franchise, appearing in the first Saw film.

Design and Function

The Quadruple Shotgun Trap was a security trap set up in a hallway in Jigsaw's hideout. It consisted of four double-barreled shotguns suspended from a wooden ceiling beam. The trigger of each shotgun was connected to a tripwire which was strung across the hallway below. When a victim stepped on the tripwire, the shotguns would go off simultaneously and kill the person below. (Saw)


Jigsaw's Hideout

Early on in his series of murders John Kramer, better known as the Jigsaw Killer, had a hideout inside an abandoned mannequin factory at 213 Stygian Street. One night, Detective David Tapp and Detective Steven Sing managed to deduce the location of the hideout by further examining a video tape left by Jigsaw at the crime scene of one of his previous game. Minutes later, they arrived at the factory and entered the building. When they went upstairs and searched the hideout, they found a box with little figures resembling another deadly game Jigsaw had already planned for the future. Furthermore, they found one of the pig masks he used for his abductions, as well as the mechanical ventriloquist puppet from the video. Moments later, they were startled by a noise nearby, coming from under a large red hood. Eventually, this turned out to be the voice of Jeff Ridenhour, a man who was strapped to another one of Jigsaw's chair. However, when they wanted to free him, they suddenly heard the elevator and Tapp told Sing to go into hiding to see what Jigsaw was going to do. Eager to finally arrest the Jigsaw Killer, Sing initially refused to follow Tapp's order, but eventually decided to do so and put the cloth back on Jeff, before quickly going into hiding with Tapp.


Sing's corpse

Moments later, a hooded man, Jigsaw, arrived and approached Jeff. When he told Jeff that he had planned a bigger test for him, Jeff started to cry. Moments later, the detectives came out of their hiding spot and held Jigsaw at gunpoint. However, Jigsaw managed to activate Jeff's trap, which caused the two drills to approach his head, giving the detectives merely 20 seconds to save him. While Tapp took care of the killer and held him at gunpoint, he demanded Jigsaw to tell Sing how to stop the trap and was told that only a key could unlock the metal neck brace which held Jeff's head in place. When Sing found a set of keys in a box, he desperately tried to find the right one among the dozens of keys. Having only a few seconds left, Sing eventually decided to shoot the drills, saving Jeff's life in the process. However, Tapp was distracted by the gunshots, giving Jigsaw the chance to slash his throat with a hidden blade. As he ran away, Sing immediately pursued him and eventually managed to shoot him in a hallway, causing him to collapse. Thinking that Jigsaw was dead, Sing approached him but unwittingly walked right into a booby trap and was fatally wounded by four shotguns. After Sing's death, Jigsaw, who wore some kind of body armor under his cloak and therefore remained unharmed by the shot, stood up and left the hideout, leaving the detectives and Jeff behind. Moments later Tapp, weakened by his injury, found the corpse of his dead friend and partner and subsequently suffered a mental breakdown. Later that night, Tapp and Jeff were eventually found and saved by the Metropolitan Police Department, while Sing's body was taken to the morgue, where Dr. Adam Heffner performed the autopsy on his body.

Saw: The Video Game

A similar trap was used in Saw: The Video Game to secure several hallways and passages inside the abandoned Whitehurst Insane Asylum. However, as opposed to the original trap, this one consisted of only two shotguns, which were positioned on the left and right side of the secured passage rather than above. Tapp encountered several of these booby traps during his game at Whitehurst and had to deactivate them in order to continue his way unharmed. However, he was also able to set up these traps on his own to kill other prisoners that were hostile towards him.

Saw II: Flesh & Blood

Traps that were similar to the ones from the first game were encountered by Michael Tapp numerous times throughout his own series of tests in Saw II: Flesh & Blood. The death of Sing was also mentioned in a report by Detective Allison Kerry.


  • According to the audio commentary of the first film and several interviews, the creators wanted a trap that consisted of two plates that would spring from the walls, snap shut on Sing and fold him up into a box. It was described as an iron cocoon. However, the crew decided against the idea as it would have cost too much money for visual effects. A similar idea was later be brought up for the original concept of The Rack in Saw III, but was eventually scrapped as well.
