the straitjacket

The straitjacket—also called the nut-coat, the quiet-down coat, or the canvas coat—is a restraint garment used on E Block at Cold Mountain Penitentiary to subdue condemned prisoners who become violent or uncooperative. It is a white, double-sewn canvas jacket with buttons, snaps, and buckles running up the back, designed to immobilize the wearer's arms by pinning them tightly against the torso. The jacket is stored in the restraint room, a padded cell at the far end of the Green Mile, alongside other cleaning equipment and craft items. Its deployment is a practiced routine for the block's regular guards, particularly Paul Edgecombe and Brutus Howell, who have drilled the application until it becomes a science, as efficient as a vaudeville dance routine.

Design and Purpose

The straitjacket is a canvas coat that fastens up the back, with sleeves that force the wearer's arms into a crossed, hugging position. Cuff-straps link the wrists together, and additional straps secure the arms to the sides. The jacket is intended for prisoners who pose an immediate physical threat, such as those who attack guards or other inmates. It is not a punishment in itself but a temporary measure to prevent harm and restore order. The restraint room, where the jacket is kept, has soft walls to prevent self-injury, and the jacket is used only when verbal de-escalation fails. The guards know how to "zip a problem child into that jacket lickety-larrup," reflecting their efficiency with the device.

Use on William Wharton

William Wharton, a violent and unpredictable prisoner who fancies himself Billy the Kid, is the most frequent recipient of the straitjacket on E Block. After he urinates on Harry Terwilliger's pants and shoes, Edgecombe retrieves the jacket from the restraint room and, with Howell, subdues Wharton. Howell knocks Wharton semi-conscious with a baton, then the two guards work in practiced tandem: Howell sits Wharton up and holds out his arms, Edgecombe rams the sleeves up his arms, and Howell does up the buckles up the back. Edgecombe then grabs the cuff-straps, pulls Wharton's arms around his sides, and links his wrists together with another canvas strap, leaving him "looking like he was hugging himself." Wharton is then dragged to the restraint room, where he spends hours or days in the jacket, sometimes raving, sometimes silent. The jacket is used again after Wharton spits a liquefied moon-pie into Howell's face, and again after other outbursts, each time with the same efficient procedure.

Use on Percy Wetmore

On the night of the journey to save Melinda Moores, the straitjacket is used on Percy Wetmore, the cruel and politically connected guard who sabotaged Eduard Delacroix's execution. Edgecombe, Howell, and Harry Terwilliger corner Percy in the office, where he is reading a pornographic comic book hidden inside a medical text. When Percy refuses to cooperate and screams for help, Howell twists his ears until he submits, sobbing. Edgecombe slips the sleeves up Percy's arms, Howell yanks his hands around to his sides, and Terwilliger does up the back and snaps the cross-straps. The entire process takes less than ten seconds. Percy is then locked in the restraint room, where he spends several hours in the dark, wearing the jacket and licking at the tape over his mouth. The jacket here serves as ironic punishment: the same device used to control violent prisoners is applied to the guard who abused his authority.

Symbolic and Narrative Significance

The straitjacket functions as a symbol of control and power reversal on the Green Mile. For Wharton, it represents the guards' ability to contain his wildness, reducing him from a raging psychopath to a helpless, bucking figure. For Percy, it inverts the power dynamic: the guard who relished beating prisoners with his hickory baton is himself rendered powerless, wrapped in canvas and locked in the dark. The jacket's application is a ritual of authority, but its use on Percy exposes the arbitrary nature of that authority—the same men who enforce order on the condemned can, when necessary, turn that order against one of their own. The jacket also underscores the theme of restraint versus freedom: the condemned prisoners, though physically confined, retain a measure of dignity and choice, while Percy, stripped of his baton and gun, is reduced to a whimpering, helpless figure. The straitjacket, in its crude canvas simplicity, becomes a tool not just of physical control but of moral reckoning.
