100 pieces for Jack of Plate

Build an Elizabethan-style jack of plates for your next reenactment or SCA kit. Our 1.25-inch square armor plates give you the pieces to get started. They can also be the foundation for a LARP costume with a historical feel.

Jacks were worn by ordinary soldiers in 16th-century England and Scotland, with small plates sewn between layers of fabric. The Royal Armouries example from about 1580 shows how those plates became a wearable garment.

Quality in every plate

• Industrial laser precision. Every plate is cut on an industrial laser for consistent geometry and clean edges with micron level precision.
• Thorough tumble finishing. Plates are media tumbled to smooth cut edges, round corners, and create a clean matte finish.
• Final quality control. We check every plate by hand as we pack them making sure only the best make it to you. 
• A little extra. We always pack a few extra pieces per 100 just to make sure. If for some reason a plate or two make it through QC, don't worry you got more than you ordered in your shipment. 

What comes in a pack

100 plates per pack. Each plate measures 1.25 inches square. See the drawing for the plate shape and attachment holes.

Pick your material

• 304 stainless steel: 1.2 mm / 0.048 inch.
• Heat-treated 410 stainless steel: 1.0 mm / 0.040 inch.
• 6061-T6 aluminum: 1.6 mm / 0.063 inch.

Aluminum is the lightest option. Our 410 stainless is hardened and tempered, with a tumble before heat treatment and another afterward. It can have a darker finish that varies from batch to batch.

For combat builds, choose your material and construction to suit your group's armor rules.
