This compression provides a secure, non–slip hold even as the tube diameter varies slightly due to manufacturing tolerances.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"chq-answer-block chq-reveal chq-reveal-d1\"\u003e\n\u003ch2\u003eHow Do Expanding Stem Casters Install?\u003c\/h2\u003e\n\u003cp class=\"chq-answer-direct\"\u003eInsert the rubber or nylon expanding adapter into the open end of your hollow tube leg, then tighten the bolt on top. As the bolt tightens, the adapter compresses and expands to grip the inside tube wall securely. Some designs use a wing nut for completely tool–free tightening by hand.\u003c\/p\u003e\n\u003cp class=\"chq-answer-detail\"\u003eInstallation typically takes 30 seconds per caster. No drilling, no threading required. For removal, simply loosen the bolt and pull the caster straight out.
