Round Tube Saddle Glides — Square Sled Base provides a secure, screw-fastened saddle fit for round tubing. The 25 × 25 mm square sled base delivers smooth, floor-safe gliding on hard floors and low-pile carpet, while the reinforced PA (Polyamide) construction ensures durability in high-traffic commercial environments.

Round Tube Saddle Glides — Square Sled Base are engineered for sled-base chairs and tubular furniture where long-term stability, alignment, and floor protection are critical. Standard sled glides that rely on friction or snap-fit tabs often loosen over time, rotate under lateral movement, or detach completely. In busy commercial or institutional environments, this leads to exposed metal tubing, damaged floors, and noisy, unstable seating.
Round Tube Saddle Glides — Square Sled Base (One-Hole) eliminate these issues with a precision saddle-fit designed for Ø25 mm round tubing, a reinforced square PA sled base for controlled movement, and a required screw-fastened installation that locks the glide permanently in place. Once installed, the glide becomes a fixed, aligned component of the sled frame — not an accessory that shifts or fails.
The contoured saddle wraps tightly around the tube, centering the glide and maintaining proper orientation. A single central screw secures the glide mechanically, preventing rotation, pull-off, or misalignment during repeated chair movement. The square sled base distributes weight evenly and glides smoothly across hard floors and low-pile carpet, reducing noise and surface wear.
Snap-on glides loosen. Press-fit glides drift. Soft materials flatten and wear out.
Round Tube Saddle Glides — Square Sled Base are built for environments where seating is moved constantly, and failure is not an option.
If your sled-based furniture keeps losing glides…
If exposed tubular legs are scratching floors…
If you need a secure, screw-anchored solution for daily use —
This glide is designed for permanent, high-use performance.
With the glide mechanically locked in place, alignment stays consistent, movement stays smooth, and floors remain protected — even under heavy commercial traffic.
The contoured saddle is shaped specifically for Ø25 mm round tubing, ensuring a snug, centered fit. Once installed, the glide cannot twist or drift, maintaining correct alignment throughout the life of the furniture.
The square sled base provides a stable contact area that distributes weight evenly and reduces pressure points. This improves glide consistency, minimizes noise, and protects both hard flooring and low-pile carpet.
A single central mounting hole ensures the glide must be fastened with a screw during installation. This mechanical lock prevents rotation, loosening, or accidental removal — a necessity for schools, offices, and institutional seating.
The Polyamide construction offers high tensile strength, excellent impact resistance, and superior abrasion resistance. Its low-friction surface allows smooth sliding while resisting moisture, cleaning chemicals, and daily wear from –40 °C to 85 °C.
The combination of a contoured saddle and screw-fastened attachment creates a mechanically locked system. This prevents twisting, uneven wear, and detachment — even under repeated lateral and forward movement.
The square sled base minimizes drag noise and protects flooring from scratches or gouging, making it ideal for classrooms, offices, waiting areas, and hospitality seating.
