Custom Capsule and Slot Parts
Custom Capsule and Slot Parts
A capsule is a rectangle with fully rounded ends, also called a slot, oblong or stadium shape. Enter the total length from end to end and the width, and the quoter rounds the ends for you.
Capsule shapes are used for name tags and badges, drawer and cabinet pulls, labels and signs, cable and strap guides, sliders, wear pads and covers. For a capsule with a slot cut out of the middle, use ring capsule parts.
Measuring: total length runs tip to tip across both rounded ends. Width is across the straight section, and the end radius is always half the width.
Materials: Acrylic in clear, frosted, white, black and colors (acrylic edges come out flame-polished), polycarbonate, glass and mirror, plus neoprene, EPDM, silicone, Buna-N, cork and fiber.
How it's made: every part is CNC cut (laser, waterjet, and more) to ±0.015″. No minimum order.
What you enter: Total Length, Width. Pick inches or mm in the quoter.
Size: Up to 32.5″ × 32.5″ for most materials. Glass, mirror, polycarbonate, Viton and PTFE top out at 18″ × 12″, and borosilicate at 12″ × 12″; the quoter shows the exact limit for each material.

How to measure
- Measure the finished cut size you need, not the rough stock.
- Discs: diameter across the widest point. Rectangles: length × width. Rings: outside diameter (OD) and inside diameter (ID). Other shapes: follow the fields on that product.
- A tape measure is fine for most parts. Calipers help on small pieces.
- Pick material and thickness in the quoter.
- Fully custom shape? Upload a DXF. No CAD? Send us a sketch with measurements.
