4.5" OD Surface-Mount Steel Chain Bollard with Slotted Silver Cap – Yellow, 36", 42" or 48" H

4.5" OD Surface-Mount Steel Chain Bollard with Slotted Silver Cap – Yellow, 36", 42" or 48" H

The 4.5" OD Surface-Mount Steel Chain Bollard with Slotted Silver Cap combines a heavy-duty steel bollard with an integrated chain-management system for creating visible barriers around workstations, machinery, restricted areas, pedestrian zones, and other indoor or outdoor spaces.

Available in 36", 42", and 48" heights, each bollard is manufactured from Schedule 10 carbon steel and welded to an 8" × 8" × 5/8" steel base plate. Four pre-drilled 1" mounting holes provide clearly defined anchor locations for installation on a suitable concrete surface.

The distinctive removable silver steel cap incorporates four chain slots and is secured with a socket set-screw. Chain can be positioned through the slots to connect adjacent bollards, while excess chain can be stored inside the hollow post before the cap is reinstalled.

Available Heights

Choose the height that best fits your application. All three variants share the same 4.5" outside diameter, Schedule 10 construction, welded base plate, yellow powder-coated finish, four-slot removable steel cap, and manufacturer-stated impact resistance.

• 36" Height: Model BOL-JKS-36-4.5 – 24 lb
• 42" Height: Model BOL-JKS-42-4.5 – 26 lb
• 48" Height: Model BOL-JKS-48-4.5 – 42 lb

Features & Benefits

• Integrated Chain Slots: Four slots in the removable steel cap allow compatible chain to be routed between bollards to create visible barriers.
• Internal Chain Storage: Excess chain can be stored inside the hollow bollard when the installation configuration allows.
• Removable Silver Steel Cap: Bolt-on cap is secured with a socket set-screw and can be removed for chain access.
• Heavy-Duty Steel Construction: Welded carbon steel construction provides a durable bollard for commercial and industrial environments.
• 4.5" Outside Diameter: Provides a substantial and highly visible post for barrier and access-control applications.
• Three Height Options: Available in 36", 42", and 48" configurations.
• High-Visibility Yellow Finish: Powder-coated safety yellow helps make the bollard easy to identify in vehicle, equipment, and pedestrian areas.
• Surface-Mount Design: Welded base plate allows installation on a suitable existing concrete surface without embedding the pipe below grade.
• Pre-Drilled Base Plate: Four 1" diameter mounting holes provide clearly defined anchor locations.
• Indoor or Outdoor Use: Suitable for warehouses, machinery areas, workstations, pedestrian zones, and other interior or exterior applications.
• Made in the USA: Proudly manufactured in the United States.

Integrated Chain Barrier System

The removable cap incorporates four chain slots that allow compatible chain to connect one bollard to another. This makes it possible to create a clearly defined barrier between posts for access control, pedestrian guidance, equipment separation, or temporary restricted areas.

To configure the barrier, remove the silver top cap, position the chain through the appropriate slots, place any excess chain inside the hollow bollard, and reinstall the cap. The slots help retain the chain in position between adjacent posts.

Chain is not specified as included with the bollard and should be selected separately according to the intended application.

Surface-Mount Installation

Each bollard is welded to an 8" × 8" × 5/8" steel base plate containing four 1" diameter pre-drilled mounting holes. The surface-mount design allows the bollard to be anchored to a suitable concrete surface without embedding the pipe below grade.

Anchoring hardware is not listed as included and should be selected according to the mounting surface, substrate condition, and project requirements.

Common Applications

• Machinery and equipment areas
• Warehouse workstations
• Pedestrian guidance and separation
• Restricted-access areas
• Loading and receiving areas
• Maintenance and service zones
• Outdoor work areas
• Commercial facilities
• Industrial properties
• Temporary or permanent chain barriers

High-Visibility Powder-Coated Finish

The safety-yellow powder-coated finish provides a durable exterior with strong visual contrast, helping the bollards stand out in warehouses, equipment areas, pedestrian zones, and other busy environments.

The contrasting silver steel top cap also makes the chain connection point easy to identify during setup or reconfiguration.

Removable Slotted Steel Cap

Each bollard includes a removable silver bolt-on steel cap with four chain slots. A socket set-screw secures the cap to the bollard while still allowing it to be removed when the chain arrangement needs to be changed.

This design provides greater flexibility than a permanently welded cap and allows excess chain to be stored inside the bollard when appropriate.

Impact Resistance

The manufacturer lists an impact resistance of 4,000 lb at 4 mph for this steel bollard series.

Actual performance depends on installation conditions, anchoring, substrate, and other project-specific factors. This product should not be represented as crash-rated or vehicle-rated beyond the manufacturer-stated specification unless additional certified testing documentation is available.

Made in the USA

These steel chain bollards are proudly manufactured in the United States for commercial and industrial applications.
