JI4-28RDTP17 Round Pedestal Table Base
JI4-28RDTP17 Round Pedestal Table Base blends a compact profile with serious stability for dining rooms. The domed, round footprint plants firmly on imperfect floors. Five contact points make leveling fast and precise. A four inch column ties the plate and spider with tight rigidity. The seventeen inch top plate centers force and protects edges. Crews assemble the three piece kit with bolts and clear indexing. Black powder coat resists wear and daily cleaning. Guests enjoy open leg space without prongs in tight aisles. Designers get a clean pedestal look that suits modern or classic tops. Operators gain reliable performance in busy front of house zones.At a Glance
28″ round base, domed underside. TP17 spider. 4″ column. Five adjustable glides. Dining height 29″. Cast iron with textured black finish.
What It Is
This model comes from the Round Series for compact and mid size tops. The dome concentrates mass near the floor for steady footing. Five glides support the plate at balanced points. You dial level quickly on tile, wood, or concrete. The four inch column resists sway when guests shift or lean. A seventeen inch spider spreads screws across a safe circle. That pattern reduces peel at corners and long grain edges. The round pedestal keeps chair paths smooth on all sides. Servers move trays without clipping prongs at ankles. Cleaning stays simple because the base has no pockets. Installers join the plate, column, and spider with through bolts. Parts index cleanly for fast, repeatable assembly. When spans grow wider, compare the pronged sibling JI4-36TP24 for extra reach. Tricky slabs may also benefit from self leveling help like CT2086.Key Specs
Overall height measures twenty nine inches for dining. The footprint measures twenty eight inches in diameter. Cast iron supplies mass for vibration control. Unit weight averages about seventy eight pounds per base. The column measures four inches in diameter with strong wall thickness. The TP17 spider uses slotted holes for flexible patterns. Slots fit common restaurant mounting points and fastener maps. Hardware clamps joints with high tensile bolts and threadlocker. Five plastic glides adjust independently for fine tuning. The dome geometry keeps the plate rigid under load. Flat pack shipping protects edges and finish. Crews move cartons with dollies or two person lifts. Clear labels guide room by room deployments. For problem floors, a compact stabilizer like CT2071 can help.Installation Reminder
Verify pilot sizes before mounting. Level each glide, then torque bolts in a star pattern. Recheck level and fasteners after the first service week.
Recommended Top Sizes
Round tops up to forty two inches pair well with one base. Many forty eight inch rounds also work within a careful envelope. Heavier materials increase leverage during service. In those cases, move to a larger spider or paired bases. Square tops need close attention to chair clearance. The pedestal keeps corners open and neat for seating. Rectangular tops under twenty four by thirty inches usually fit a single base. Longer rectangles often require two bases and a center line. Even spacing reduces bounce at spans and edges. Guests feel steady plates and calm glassware at all seats. Hosts gain smoother turns when tables stay level. For very heavy spans, review the heavy duty JI5x1.5-36TP24 option.Options, Siblings, and Variants
Upgrade the top plate to twenty four inches when tops grow heavier. That upgrade spreads screws and limits edge flex. Bar height builds add a tall column while keeping the footprint. Footring options support posture at tall seating. Stainless siblings provide a brushed look for damp zones. Designers often compare this model with JI4-28RDTP17 refinements for styling choices. Larger projects can also mix in JI4-36TP24 to support wider tabletops. Layout teams add floor aids like CT2086 when level conditions shift.Design Insight
Center the plate under chair arcs, not just under the top. Test stool clearance at all angles. Mark final glide positions before torque.
Why Specify This Base
Stability and comfort drive the choice here. The round plate lowers tip moments at edges during use. Five glides counter irregular floors without shims. The pedestal opens leg space for compact layouts. Guests approach from any side with relaxed posture. A four inch column keeps the joint stiff at height. The finish hides wear and cleans fast between turns. Install time stays short because parts index clearly. Field swaps remain simple with familiar hardware. Managers see fewer wobble tickets and faster resets. Over time, reliable footing protects guest ratings and staff time. Rooms feel calmer when tables stay quiet during service.Reasons to Choose TimeWorn
We align plate size, hole maps, and fasteners before production. Samples confirm finish sheen and texture under your cleaners. Clear diagrams ship with every crate for fast staging. Our team tracks schedules and logistics in writing. Hardware packs arrive labeled for specific rooms. Crews level tables quickly with our simple guides. We support multi site rollouts with consistent patterns. The result reduces punch items and field labor. Your team spends more time with guests, not repairs. The process protects opening timelines and long term value.Pro Tip
Keep spare glides in the host kit. Swap worn feet during resets to preserve level and stop creeping rock.
Why the JI Platform Works
Geometry, mass, and parts commonality build a strong system. Circular plates resist torsion from any seating angle. Wide spiders distribute screws to reduce peel and stress. Columns move load smoothly into the plate and floor. Glides allow micro corrections in seconds. Bolt up construction keeps service predictable and quick. Shared parts across models shorten training for techs. Designers hold a unified look across varied sizes. Operators phase changes with minimal disruption. Guests notice quiet, steady tables and clear leg room.Featured Answer
When should I choose this round base?
Use it for rounds to forty two inches, and many forty eights. Step up the spider or add a second base for heavier materials.

What tabletop sizes fit JI4-28RDTP17?
One base pairs well with round tops up to 42″, and many 48″ rounds within a careful envelope. For heavier materials or wider spans, step up to a 24″ spider or use paired bases.
How does the five-glide dome base handle uneven floors?
The domed 28″ plate uses five independently adjustable glides for micro-leveling on tile, grout, wood, or concrete. Crews remove “creeping rock” without shims for a steady feel at every seat.
When should I upgrade to a 24″ top plate?
Upgrade when tops are heavier (stone, thick slabs) or when guests rest weight near edges. A 24″ spider spreads screws across a wider circle, improving edge stiffness and reducing wobble.
What installation steps do you recommend?
Verify pilot sizes before mounting. Level each glide, then torque bolts in a star pattern with threadlocker. Recheck level and fasteners after the first service week for a stable start.
How should the finish be cleaned and maintained?
The textured black powder-coat hides scuffs and wipes clean with standard non-abrasive cleaners. Avoid harsh solvents or wire pads. For full guidance, see Care & Cleaning.
