Ingersoll Rand 22040778 3-Piece Sign Post Driver | 7 - 3/4" Under Collar Length | 7/8" x 3 - 1/4" Hex Shank

Installing sign posts with compatible pneumatic pavement breakers calls for an attachment that transfers impact energy to the post while matching the tool's shank and retainer arrangement. The Ingersoll Rand 22040778 3-Piece Sign Post Driver is designed for sign-post driving applications and features a 7/8" x 3-1/4" hex shank with a 7-3/4" length under the collar. The hex shank is the portion fitted into the pneumatic tool, while the under-collar measurement identifies the attachment's working length beneath its retaining collar. This configuration is intended for crews installing sign posts during roadway maintenance, construction, and site improvement projects.

Unlike a single-piece driving steel, the 22040778 includes three components: a shank, post block, and 3-1/2" driver. This arrangement provides the components specified by Ingersoll Rand for transferring repeated impact blows to a sign post. The manufacturer's catalog lists a 5 lb weight and box quantity of 1 for this configuration. Other versions are offered with larger hex shanks, allowing buyers to select the correct attachment for their existing pneumatic breaker rather than assuming different shank sizes are interchangeable.

FAQs:

• Q: What is included with Ingersoll Rand part number 22040778? A: The manufacturer identifies this as a three-piece sign post driver that includes a shank, post block, and 3-1/2-inch driver. The published box quantity is one complete assembly.
• Q: What pneumatic tool shank does the 22040778 use? A: It has a 7/8-inch hex shank measuring 3-1/4 inches in the manufacturer's shank-size designation. Check the breaker or digger's tool holder and retainer specifications before purchasing.
• Q: Does 7-3/4 inches refer to the overall attachment length? A: No. Ingersoll Rand specifies 7-3/4 inches as the length under the collar, not necessarily the total assembled length. The collar is part of the tool's retention interface.
• Q: Can this sign post driver be used for all sign-post profiles? A: The catalog identifies a 3-1/2-inch driver but does not specify every compatible sign-post shape or size. Confirm the post profile, driving arrangement, and tool manufacturer's instructions before use.
• Q: Are sign post drivers available for larger breaker shanks? A: Yes. Ingersoll Rand lists related three-piece sign post drivers with 1-inch by 4-1/4-inch, 1-1/8-inch by 6-inch, and 1-1/4-inch by 6-inch hex shanks.
