Hypersonic Car Bumper Corner Antenna Poles 2-Pack — Adjustable 11–23" Telescoping Parking Markers, Foldable

These two adjustable bumper corner antenna poles from Hypersonic are simple, visible markers that attach to your car’s bumper to help you judge corners and reduce low-speed scrapes when parking or maneuvering.

If you’re learning to park, driving a compact vehicle, or routinely squeezing into tight spaces, a clear exterior reference on the bumper makes judging distance and corner position much easier. The Hypersonic 2-pack includes two stainless-steel poles with plastic bases that mount to horizontal bumper areas, telescoping from about 11" up to 23" and folding for car washes. They’re designed to be a low-cost visual aid for drivers who need a consistent cue for where the vehicle’s edge sits.

How will these bumper poles help when I park?

The antenna poles create a fixed, visible endpoint at each corner of the bumper so you can tell from the driver’s seat how close the car’s corner is to obstacles. That visible anchor reduces guessing and the chance of light collisions when entering tight spots.

• Provides a top reference point you can see from inside the cabin
• Adjustable height to match your driving position and sightline
• Helps prevent bumper scrapes during low-speed maneuvers
• Foldable for passing through car washes or low clearance

Will these fit my vehicle and how do they attach?

The Hypersonic poles are built for universal horizontal bumper mounting and work with most cars that have a flat or slightly curved bumper edge. The base is plastic with a stainless-steel pole that slides into the mount; installation requires a clean mounting surface and firm adhesion for best hold.

• Universal fit for horizontal bumper edges on most cars
• Stainless-steel rod with plastic base for durability
• Installation requires surface cleaning and 24-hour curing time
• Not recommended for irregularly angled or heavily textured bumpers

How adjustable and durable are these parking markers?

The poles extend from about 11 inches to 23 inches so you can set a visible height that suits your driving posture. The stainless-steel shaft resists bending in normal use, and the base allows angle adjustment; the top is not reflective or illuminated, so it’s a daytime or well-lit reference.

• Telescopes between 11" and 23" to suit driver sightlines
• Angle-adjustable bottom for precise corner alignment
• Folds down for car washes or low clearances
• Top is non-reflective—best for daylight or lit environments

What should I know before installing and using them?

Proper surface preparation and a full curing period are key to a secure bond. Clean the mounting area thoroughly, let the adhesive cure for 24 hours before driving, and avoid washing the car on the same day to prevent dislodging. If installed incorrectly the pole may fall off, so check the fit after the initial drive.

• Clean mounting area before attachment for strongest adhesion
• Do not remove or drive the vehicle for 24 hours after installation
• Avoid washing the car the same day you install the poles
• Verify correct installation to prevent accidental loss

Who is this for: Drivers learning to park, new license holders, owners of compact cars, or anyone who wants a low-cost, non-electronic visual guide to where their vehicle’s bumper corners end. These markers are especially useful for shorter drivers, drivers who routinely park in tight urban spaces, or fleet vehicles where consistent corner reference reduces minor scrapes. If you need nighttime illumination, reflective or lighted markers may be a better choice; the Hypersonic poles are best used during daytime or in areas with adequate lighting.
