We Withdaw Our 50-Year 'Request'. Born from the Reflection of a Manufacturer that Kept Saying 'Don't Turn It', the Next-Generation Tension Rod 'Goku-pita', Which Resists Falling Because You Turn It, Begins Exclusive Pre-Sales at Cainz on April 22

Heian Shindo Kogyo Co., Ltd. (Headquarters: Osaka City, Osaka; Representative Director: Kayoko Takeuchi) has developed a new product, "Goku-pita," which structurally solves the biggest problem with tension rods: "sudden falling."

Starting Wednesday, April 22, 2026, exclusive pre-sales will begin at Cainz stores nationwide (*1) and the official online shop of Cainz Corporation (Headquarters: Honjo City, Saitama; Representative Director & CEO: Masayuki Takaya).

It has been 50 years since the birth of the tension rod. This product fundamentally reviews the structure, inventing a new mechanism that turns the "incorrect" installation method—which everyone intuitively does—into the "correct" one. It achieves overwhelming load-bearing capacity, approximately double that of conventional products (*2). We propose a new standard for tension rods that frees you from the stress of a sudden "crash" fall.

"It won't fall if used correctly." The conflict of a manufacturer that couldn't face users for 50 years.

When installing a tension rod, do you extend its length by "turning it around and around" between the walls and fix it as is? Actually, this is the wrong way to use a conventional spring-type tension rod.

[✖ The intuitive mistake many people make] Placing the pipe between the wall and wall, turning it around and around to extend its length and make it tense.

[〇 The original correct installation method] Extending it to be "a few centimeters longer" than the width of the wall in advance, and installing it while pushing the spring in.
