Built Like A Tank Black HDPE Square Bollard Post Cap To Pour Concrete Inside For Rock Hard Impact Deflection And Premium Heavy Duty Outdoor Gate Security
✔️ Heavy grade polymer housing fits standard gate posts securely
This removable cover seals the top of standard square steel tubes while letting you drop liquid concrete straight through the opening. Property owners and contractors install them on driveway gates and perimeter fences to create solid anchor points that stop ram raids cold.
✅ Measures 5-1/4 inches wide to match standard rectangular tubing✅ Matte black finish resists fading under direct sunlight exposure
✅ Lightweight snap-on cover slides off quickly when filling mortar
✅ Slip-resistant lip prevents accidental drops during installation
💡 How do I properly secure a hollow metal bollard against impact damage?
Tamping a solid filler changes how the entire frame absorbs sudden force.
You get a rigid barrier that pushes back hard against bumpers during low-speed collisions.
Watch these steps to handle the job smoothly:
- Mix fast-hardening grout until it flows easily into the core cavity
- Lay steel rebar sections crosswise before the slurry sets up completely
- Scrape off excess material so the outer rim stays flush with the post edge
- Give the assembly seventy two hours to cure before leaning anything heavy against it
