Key Features

• Sturdy aluminum and steel construction: Built with aluminum and solid steel parts to withstand repeated use and provide a reliable, long-lasting clamp for large-format papers.
• One-inch clamp opening: The jaws open to about 1 in so it can securely hold several sheets or a thinner stack of large documents without slipping.
• Snap-on plastic label holder: Includes a label pocket that lets users identify sets quickly, improving organization on blueprint racks or wall displays.
• Includes tightening wrench and wing knobs: Comes with a wrench for assembly and silver wing knobs that allow firm tightening so the clamp stays closed during handling or hanging.
• Multiple size options available: Sold in a range of lengths so buyers can choose 18 in, 24 in, 30 in, 36 in, or 42 in clamps to match different drawings and poster sizes.
• Compatible with racks and hanging systems: Designed to fit most blueprint storage racks and poster display systems to maximize workspace efficiency.

Who It's For

This clamp suits architects, engineers, construction site managers, repro houses, and graphics shops that regularly store or display large-format plans, posters, or maps. It works especially well where space is limited and documents need to be hung or filed upright on racks for quick access.

Those who need heavy-duty clamping for very thick, heavily used sets or expect industrial-level abuse might prefer a commercial-grade or spring-loaded clamp system; likewise, users who want a softer, non-metal finish for studio display may want to look at lighter presentation clips.
