Square Stainless Bar Base
The Square Stainless Bar Base delivers modern form and commercial-grade stability for bar-height tables. This stainless model combines clean geometry, structural strength, and premium finish. The square-column design keeps lines crisp while aligning neatly with booth edges or bar counters. Available in 18×18 and 22×22 footprints, it anchors high-top surfaces with precision and balance, creating a unified aesthetic across your dining areas.
What It Is
The JIS3SQ-18SQTP17BH and JIS3SQ-18SQTP17BHFR models belong to JI Bases’ stainless steel square-footprint line. Each includes a 3×3-inch square column and 17-inch top plate for consistent support. The bar-height version (BH) stands 40.5 inches tall, while the BHFR variant adds a welded 19-inch footring for added guest comfort. These models align well with dining-height options such as the JIS3-18TP12 / JIS3-22TP12 stainless four-prong bases, which share a similar aesthetic for uniformity between table heights.
At a Glance
Bar height 40.5″. 3″×3″ square column. 17″ top plate. 18×18 or 22×22 stainless footprint. Optional footring. Brushed #304 stainless finish.
Size & Compatibility
Both the 18×18 and 22×22 square plates are crafted from #304 stainless steel with a cast-iron top plate for secure mounting. Each includes four adjustable plastic glides for leveling. These models complement dining-height bases like the JIS3RD-18SQTP12 / JIS3RD-22SQTP12 stainless square family, which use the same brushed finish and squared footprint at standard table height. The cohesive design allows seamless transitions from dining to bar height, maintaining a consistent visual rhythm across layouts.
Recommended Top Sizes
Manufacturer guidelines show that the 17-inch top plate with square column can support tops up to roughly 36 inches square. Larger or heavier tops may require multiple bases for balance. When used in bar-height layouts, the combination of a heavy base plate and square column minimizes flexing under dynamic loads. Designers often coordinate these models with round-column stainless options like JIS3-18RDTP12 / JIS3-22RDTP12 to achieve a mixed geometry look while preserving uniform stainless tone.
Design Insight
Square bases align with architectural grids and parallel booth lines, reinforcing balance and symmetry in hospitality interiors.
Installation and Setup Tips
Position the base on a level floor before mounting the tabletop. Pre-drill all holes to ensure accurate alignment and even load transfer. Adjust glides until all four corners rest evenly. When using the footring model (BHFR), ensure the ring faces outward before tightening. Multi-base installations should maintain equal center spacing for symmetry and comfort. Tighten hardware only after final level checks to prevent torsion stress during assembly.
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
Clean the stainless finish with mild detergent and a soft cloth. Follow the grain to preserve the brushed surface. Avoid acids and abrasives. Inspect glide height and fasteners regularly to maintain level stability. Tighten bolts every few months to prevent tabletop movement, especially in high-traffic areas.
Featured Answer
Why choose a Square Stainless Bar Base?
It combines architectural style with lasting strength. The square column design creates precision alignment and reliable balance for bar-height installations.
Options and Variants
This stainless series offers dining and bar-height options, as well as round or square column styles. For elevated applications, consider pairing the bar-height version with JIS3-18TP12BH / JIS3-18TP12BHFR to maintain the same stainless finish and geometry across zones. Designers who prefer a different base style may explore four-prong stainless families, which share matching column diameters and compatible mounting patterns.
