Look Inside the Book

Every page has one big drawing and a box with the numbers and steps you need to know:

Legs, diagonals, horizontals and splice plates labeled, plus the 5,000 lb anchor rule.

These are real pages from the book. The table of contents is the full one: 8 parts and 60 topics.

The Problem Isn't You. It's How It Was Explained to You.

You have a practice question in front of you: max free fall, max arresting force, max deceleration distance. Three numbers. You went over them last week, and now they all run together.

No surprise there. The regulation buries them in long sentences, between paragraph numbers and exceptions, with nothing to look at and nothing to hang them on.

6 ft free fall · 1,800 lb force · 3.5 ft deceleration, drawn on one falling climber

In the book, those limits are one page: one falling climber, with 6 ft, 1,800 lb and 3.5 ft marked right on the drawing, each one where it happens: before the lanyard catches, at the harness, and while the absorber stretches.

Every topic works the same way: the harness and its D-rings, the clearance ruler, 100% tie-off, the two-leg bridle at 45°, the FCC RF limits. Each one on its own page.

You see where each number sits, you understand why it's there, and you answer the question without going back to the CFR.

Same Topic, Two Ways to Study It

  • The manual: line after line
  • D-rings and connectors explained only in words
  • You show up to the exam with doubts
A full-body harness shall incorporate attachment elements designated for specific applications. The dorsal D-ring, located between the shoulder blades, is the attachment element intended for connection to a personal fall arrest system. Side D-rings, positioned at the hips, are intended exclusively for work positioning and shall not be employed for fall arrest. Sternal or front attachment elements may be utilized for ladder safety systems and certain rescue applications, while seat or suspension attachments are designated for suspended work in accordance with manufacturer instructions and applicable standards.

One Page, One Topic, All Clear

Think of it this way:

You're 120 ft up a lattice leg on a twin-leg lanyard, moving past a horizontal. One hook has to come off. Which one, and when?

In the book you open the 100% tie-off page and see it drawn: connect the new hook, check it, then release the old one, step by step on the same climber.

100% tie-off in 4 steps: connect, check, then release the old hook.

Same with the 3 OSHA fall arrest limits, the clearance ruler, the harness D-rings, the two-leg bridle at 45° and the RF signs: each one on its own page.

Tower Technician Illustrated is 8 parts and 60 topics, all drawn, with an exam review at the end: every number on one page and the clearance and rigging calculations in steps.

What you see drawn, you don't have to memorize.

Frequently Asked Questions

Is it for me if I already climb towers but never took the written exam?

Yes. It doesn't explain what a ladder is: it goes straight to what the written exam asks, like the OSHA limits, the clearance and fall factor math, WLL and RF limits, each one drawn.

Where does the content come from?

From OSHA 29 CFR 1926 (Subpart M) and 1910 (1910.140, 1910.268), ANSI/ASSP Z359, ANSI/ASSP A10.48, ANSI/TIA-222 and the FCC RF exposure rules (47 CFR 1.1310, OET Bulletin 65), checked against the editions in force when the book was written. The exam review lists every number with the section it comes from, so you can check it yourself.

Is this official material?

No. It's an independent illustrated study book, not issued or endorsed by the organization that administers the TTT-1, OSHA, ANSI, ASSP, TIA or the FCC. It doesn't give you the TTT-1 card or any certificate: you still take the exam through that organization. The book is for studying the written part.

Does it replace my climber training?

No. It's study material. It doesn't replace hands-on fall protection, climbing and rescue training, competent person oversight or your employer's authorization to climb.

Are the practice questions the real exam questions?

No. They're written for this book, in the style of a written exam, so you can test yourself topic by topic. They aren't official questions from any exam.

When and how do I get it?

The book and the 2 bonus books arrive as PDFs by email, at the address you enter at checkout.

Do I have to pay every month?

No. It's a one-time payment. No subscription.

Can I get it on paper?

We don't ship a printed book. It's a PDF by email, designed to print on regular letter paper, so you can print it and keep it in the truck, or read it on your phone at the hotel.

How does the refund work?

You have 30 days. We refund everything if the file won't open, if the book isn't what you see on this page, if you were charged twice or if the email doesn't arrive: just email us.
