Field Test Report

One hour. Six inmates.
Zero broken Toughooks.

A State of Ohio Correctional Facility designed a severe durability assessment to find out whether Toughook coat hooks could survive deliberate destruction attempts, using tools, weight and brute force.

Background

Why a correctional facility?

Correctional facilities require durable, tamper-resistant materials that can withstand extreme conditions and intentional misuse. To test the strength and resilience of Toughook coat hooks, the facility ran a severe durability assessment using the people, tools and items that would realistically be within reach.

Test setup
  1. 1
    The group
    A group of 5 to 6 inmates was placed in a room.
  2. 2
    The tools
    Various tools, equipment and items they would have direct access to were provided.
  3. 3
    The clock
    A set time of approximately one hour.
  4. 4
    The task
    Try to destroy the hooks.
Findings

Destruction attempts & results

Three categories of attack, in the facility's own words. Diagrams are schematic illustrations of each test.

1
Test 1 of 3

Bending & vise grip

No failure
Method

Inmates attempted to bend or crush the hooks by placing them in a vise and applying extreme force.

Observed result

Some hooks did bend, but returned to their original shape afterward. No hooks suffered permanent structural failure.

CLAMPING FORCE

Test 2 of 3

Load-bearing strength

No failure
Method

Facility staff mounted the hooks on block walls and subjected them to over 260 lbs of weight.

Observed result

The hooks bent and sprang back to their original form, maintaining peak condition, far beyond their official 88 lb rating.

Test 3 of 3

Hand & tool-based destruction

No failure
Attempt
By hand

An impossible task. The hooks would not break.

Attempt
Nylon string & shoelaces

Used to try to file through the plastic. After an extended period they created lacerations, but nothing structurally significant in the time given.

Attempt
Hammers

Even with hammers, inmates were unable to break the hooks.

Conclusion

Built for the worst. Ready for the rest.

Even under extreme, intentional destruction attempts with tools, weight, and brute force, Toughooks maintained their strength, shape, and function.

This case study highlights why Toughooks are trusted in high-security environments, where safety, strength and reliability are non-negotiable. If these hooks can withstand the ultimate stress test in a correctional facility, they can handle anything in schools, gyms and public spaces.
