Stainless Steel Square Column Base
The Stainless Steel Square Column Base combines strength, precision, and premium finish. This dining-height model suits modern hospitality spaces needing high-end metal accents and solid stability. The square column profile offers a contemporary look while keeping alignment clean for booth or open-floor layouts. Available in 18×18 and 22×22 footprints, it pairs perfectly with larger tabletops where added weight and footprint help balance proportion and support.
What It Is
The JIS3SQ-18SQTP17 and JIS3SQ-22SQTP17 belong to the stainless steel square-footprint base line from JI Bases. These models include the upgraded 17-inch top plate and the distinctive 3×3-inch square column. Both bring upscale polish and architectural precision to restaurant and residential dining tables. Their larger footprint ensures greater stability under heavier or longer tops, making them a practical upgrade from the JIS3-18RDTP12 / JIS3-22RDTP12 round-column series. Designers seeking a lower-profile stainless option often compare this series with the JIS3-18TP12 / JIS3-22TP12 four-prong stainless family to match style and height across multiple layouts.
At a Glance
Dining height 29″. 3″×3″ square column. 17″ top plate. Base footprints 18″×18″ or 22″×22″. #304 stainless steel finish. Four adjustable glides.
Size & Compatibility
The 18×18 version weighs about 51 lbs and supports medium tables, while the 22×22 version at 68 lbs handles larger or heavier tops. Each uses a 17-inch cast iron top plate with notched adapter and a square stainless column for precise alignment. The square geometry fits layouts where tables align with wall runs, booths, or modular seating zones. For mixed-height applications, pair these with the bar-height JIS3RD-22SQTP12BH / JIS3SQ-22SQTP12BHFR models to keep the same brushed stainless aesthetic across all seating levels.
Use Cases
This square-column base works well in restaurants, hotels, and modern residential dining areas that require clean symmetry and durable strength. The heavy base plate prevents wobble under long tables, and the brushed stainless finish blends with other architectural metals. For large shared tables, pair two 22×22 versions for excellent load distribution and guest comfort. When smaller configurations are needed, the 18×18 variant offers an equally stable but more compact footprint. The same performance standard extends to end-mount styles like JIS3-522TP12, which many designers specify for rectangular layouts requiring additional stability at the ends.
Design Insight
Square columns align beautifully with rectilinear furniture layouts and emphasize order, making them ideal for modern architectural interiors.
Installation and Setup Tips
Position each base on level flooring before attaching the tabletop. Pre-drill mounting holes to ensure even load transfer. Adjust glides so all four corners rest evenly. When pairing bases under long tops, measure center spacing to keep the mounting pattern symmetrical. Tighten fasteners only after confirming the table sits level and balanced across both bases.
Installation Reminder
Do not forget to ask us to Pre-drill your Restaurant Tables. You will spend a few hundred dollars with us, or a few thousand dollars for installers to do it during install.

Care and Maintenance
Wipe the stainless finish with mild cleaner and a soft cloth. Always follow the grain to preserve the brushed texture. Avoid acids or abrasives. Check glide height during cleaning to maintain balance and prevent uneven pressure. Routine tightening of fasteners will keep tables level and extend service life.

Options and Variants
This model family includes multiple variants: 18×18 and 22×22 footprints, both with 17-inch top plates and 3×3-inch square columns.
