Bollard Removable KeyLock 90mm In Ground - Yellow

What They Are

Bollards Removable 90mm Key Lock with Sleeve-style bollards are cylindrical steel posts about 90 mm in diameter designed to be a physical barrier against vehicles. They lock into place using a key-operated mechanism and can be removed when access is needed — giving you both security and flexibility.

Main Features

Removable Key Lock Mechanism

• The bollard slides into a ground sleeve or base plate and is locked securely with a key.

• When you want to allow access (e.g., to move a vehicle or heavy equipment), you unlock it and lift the bollard out.

• Keys are usually supplied, often “keyed alike” so one key opens many bollards.

Durable Construction

• Made of galvanised steel or stainless steel for strength and corrosion resistance.

• Often powder-coated or polished for outdoor use and long life.

• Reflective bands (Class 1) are common for visibility in low-light conditions.

Typical Specs

• Diameter: ~90 mm — gives a strong physical barrier without being overly bulky.

• Height: Usually around 900–1150 mm above ground (plus sleeve depth).

• Weight & Structure: 5mm Solid steel walls that resist impacts from cars and machinery.

Installation Options

• In-ground sleeve: core-drilled or set into new concrete/asphalt, ideal for long-term use.

• Surface mount / base plate: bolts down to an existing surface where digging isn’t practical. Examples include Removable Surface Mount Bollard with Key Lock or Removable Surface Mount Bollard ‑ Key Lock ‑ 90 Dia x 1000 m.

Commercial vs Residential Suitability

Commercial: The yellow finish makes this the usual choice for warehouses, car parks and worksites where the bollard needs to be seen as well as stop a vehicle. Popular for roller door and loading bay protection.

Residential: Works well on driveways too, though most home customers prefer the black finish for appearance. For heavier-duty protection, step up to the 114mm Platinum bollard.

Installation

Most commonly installed with an in-ground sleeve, core-drilled or set into new concrete or asphalt for a permanent, flush finish. A surface-mount base plate is an option where digging isn't practical. When the bollard is removed, the sleeve is sealed by its cover so the surface stays safe and level.

Frequently Asked Questions

How tall is this bollard once installed?

Around 900-1150mm above ground, plus the sleeve depth below the surface. Ask us if you need a specific height for your site.

Can one key open several bollards?

Yes. Keys are typically supplied keyed alike so a single key operates every bollard on your site.

Is it suitable for a warehouse roller door?

Yes - this is one of the most common uses. The yellow finish and Class 1 reflective bands keep it visible to forklifts and delivery vehicles, and it lifts out when you need full door clearance.

Can it be fitted to existing concrete?

Yes. The sleeve can be core-drilled into existing concrete or asphalt, or cast into new work. Tell us about your surface when you enquire.

Do you install, or is it supply only?

Both. Add to cart for supply-only, or request a quote for supply and installation.
