Product Features
Concentric Ribbed Compression
Formed with a series of peripheral structural fin levels that compress evenly inside cylindrical iron tubes, preventing loose structural drift or rotation.
Premium Impact PP Composition
Manufactured from specialized high-purity recycled polypropylene that absorbs heavy hammer strikes and structural dynamic weight without cracking.
Integrated Acoustic Muting
The tough polymer platform limits metal-on-metal impact, dampening rolling vibration and operational rattle inside structural frames.
Quality & Compliance
Flawless Stem Engagement: Central core socket entries are tightly held to a strict 8mm (0.315") diameter tolerance to ensure caster insertion pin engagements are secure and rattle-free.
Chemical & Moisture Resilience: The non-porous polymer core is immune to corrosion, humidity, and commercial sanitizing sprays, ensuring an extended shelf life in commercial kitchens or medical labs.
Eco-Friendly Manufacturing Standard: Produced using non-toxic recycled materials, meeting full international environmental and restriction directives.
