The TOPS TOP4150 is a carbonless 2-part memorandum book designed for efficient on-the-job memo writing and duplicate record keeping. Each page contains two 5.5 x 5 inch forms printed in blue ink, with white originals on top and canary yellow duplicates beneath. The ruled message area is large enough for clear, legible notes, and preprinted prompts — including date, to, subject, signed, and checkboxes for Please Reply and No Reply Needed — guide consistent documentation. Originals are perforated for clean removal. The book measures 11 x 5.5 inches overall and uses spiral binding to keep the duplicate copies intact as a bound reference record.
This memo book suits office administrators, field service technicians, maintenance coordinators, and any trade or business professional who needs a fast paper-based system for internal communications and follow-up tracking. The two-forms-per-page layout doubles documentation output per sheet, making it well suited for high-volume memo environments where both the sender and recipient need a copy. The bound duplicate remains in the book as a chronological record of outgoing correspondence.
Designed as a standard carbonless memo book for general office, field service, and administrative use wherever a two-part paper record system is required.
No tools or special setup required. Write firmly with a ballpoint pen on the white original to ensure a clean impression transfers to the canary duplicate below. Tear out the perforated original along the perforation line and retain the bound duplicate as a file copy. Store completed books in a cool, dry location to preserve legibility of the carbonless copies.
