Product Overview
Unused New Old Stock Lowell 16 Ratcheting Arm Cast Iron Wrench with 1-1/4 Inch Hex Opening
The Lowell Model 16 ratchet arm is a cast-iron, bolt-through industrial wrench engineered for repetitive work on large hex fasteners in mechanical, utility, and plant environments.
Lowell’s ratchet arms earned long-standing adoption in OEM and utility fleets for their replaceable enclosed gears and dependable leverage. This unused old-stock assembly, with handle 16901 paired to a 1-1/4 inch hex gear insert, sat protected in storage awaiting its first field assignment.
Product Condition
Unused, new old stock. Clean, well preserved, and shows only minor handling from storage. Maintains tight mechanical feel with no indication of wear to the enclosed gear or cast-iron body.
Product Overview
The Model 16 family combines a slim-profile cast-iron handle with a reversible ratcheting head and a bolt-through opening that allows threaded rods or valve stems to pass while tightening or loosening a nut. The 1-1/4 inch across-flats hex insert supports common fastener and valve stem sizes used in plant maintenance and utility operations. This configuration provides leverage comparable to longer wrenches while remaining compact enough for confined-space mechanical work.
The replaceable gear mechanism and field-serviceable design make Model 16 arms durable tools used where predictable torque and long service life outweigh weight or compactness considerations.

Frequently Asked Questions
Is this ratchet arm unused?
Yes. It is unused new old stock and shows only minor signs of handling from long-term storage.
What distinguishes the Model 16 design?
It uses a cast-iron body, a bolt-through head, and an enclosed reversible gear that can be replaced or serviced, making it well suited to repetitive industrial work.
What does the 16901-93320 assembly number indicate?
It identifies a 16901-series Model 16 handle paired with a 1-1/4 inch hex gear insert from the 93xxx range.
What fasteners fit the 1-1/4 inch opening?
Any nut, bolt head, or valve stem with a 1-1/4 inch across-flats dimension is compatible.
Does it have a directional control for the ratcheting action?
Yes. Model 16 arms include a reversible ratchet mechanism that allows switching between tightening and loosening without removing the tool.
Where is this style of wrench typically used?
In utility line crews, process plants, power generation facilities, water treatment systems, and mechanical shops that repeatedly work with fixed-size hex hardware.
Originally built for crews who valued rugged, serviceable tools, this Model 16 carries the durability of its era into its next workspace, ready for real mechanical duty at last.
