Ernst Manufacturing Socket Boss 3-Rail Socket Organiser Tray — Red, 40 Twist-Lock Clips, 13" Rails

The Ernst Manufacturing 8490 Socket Boss is a portable, twist-lock socket tray with three removable 13-inch rails and 40 clips that secure 1/4", 3/8" and 1/2" drive sockets for drawer, bench, or mobile storage.

Designed to maximize the storage capacity of a small footprint, the 8490 Socket Boss gives you a configurable rail-and-clip system so you can arrange, label, and transport a full socket set without wasted space. Each tray includes three universal rails that lock into the base, plus 40 twist-lock clips sized for the most common drives. Rails pop out with a push button so you can swap colors, change drive orientations, or remove racks entirely for a custom layout. The unit is compact enough for tool drawers yet rugged for workshop and field use.

How does the twist-lock system keep sockets secure during transport?

The Socket Boss uses twist-lock clips that grip sockets even when the tray is inverted, preventing rattling and accidental loss. Sockets load drive-end down so you can read sizes quickly and the molded clip geometry holds tools tightly while still allowing fast removal.

• 40 twist-lock clips included: 15 of 1/4", 14 of 3/8", 11 of 1/2".
• Clips retain sockets upside down to stop falling during movement.
• Drive-end down loading aids quick size recognition and pickup.
• Durable plastic construction resists wear from repeated insertion/removal.

Can I rearrange rails and clips to match my socket set?

Yes — the 13-inch universal rails are removable and interchangeable so you can mix drive sizes, change colors, or create specialty arrangements for impact, shallow, or deep sockets. The rails lock in place for secure storage and release with an easy-to-use push button for fast reconfiguration.

• Three removable rails let you separate SAE and metric or combine drive types.
• Push-button rail release removes a rail in seconds for reordering or cleaning.
• Molded end stops and extended socket spacing on rails for improved fit.
• Use I.D. stickers (not included) to label each clip for fast identification.

What size and capacity does the tray offer for workshop storage?

The tray measures approximately 14.88 x 5.3 x 1.35 inches, making it compact enough for standard tool drawers while still carrying a large complement of sockets. With 40 clips across three rails, this tray stores a broad mix of 1/4", 3/8" and 1/2" drive sockets in a space-efficient layout.

• Overall compact dimensions fit most toolbox drawers and shelves.
• Three 13-inch rails span the full tray length for maximum loading.
• Included clip mix supports common socket assortments right out of the box.
• Handles on each end make it easy to grab and take on the go.

How durable and supported is the product?

Manufactured in the USA, the Socket Boss is built for workshop conditions and backed by a lifetime manufacturer guarantee. Robust molded rail features and secure clip geometry are engineered to withstand repeated use and transport.

• Made in USA construction with quality-controlled manufacturing.
• Lifetime manufacturer backing for long-term ownership confidence.
• Molded end stops prevent sockets from sliding off the rail ends.
• Tray locks rails for security and unlocks with a single push.

Who is this for? The Ernst 8490 Socket Boss is ideal for mechanics, DIYers, and technicians who want a compact, configurable solution to organize mixed drive socket sets. It suits anyone who needs quick socket identification, secure transport, and the flexibility to reconfigure racks for different jobs or to keep SAE and metric sets separated. If you work in a busy shop, on-site service, or prefer orderly drawers at home, this tray gives a durable, space-saving way to store and move sockets without sacrificing accessibility.
