Blocks Larger Debris
Stiff cylindrical bristles occupy the gutter opening and help keep leaves, twigs, birds, and larger debris from collecting inside the gutter channel.
Brush-style gutter protection
LeafBlox Gutter Guards – Simple Gutter Leaf Protection
LeafBlox uses durable brush sections that sit inside the gutter to help block leaves and larger debris while maintaining an open path for rainwater. Installation requires no drilling, roof penetration, or permanent fasteners.
How LeafBlox Protects a Gutter
A simple brush design keeps the gutter opening available for water while helping prevent bulky debris from settling into the channel.
Allows Water Through
Rainwater can pass between the bristles into the gutter so it can travel toward the downspout instead of relying on a solid cover or screen surface.
Stays Serviceable
LeafBlox sections can be lifted out when maintenance is needed, shaken or brushed clean, and then returned to the gutter.
Choose the Correct LeafBlox Size
Measure the gutter opening from the rear of the gutter to the front lip. LeafBlox is offered in multiple diameters for smaller, residential, oversized, and commercial gutter applications.

Simple Installation
Clean the gutter first. Fill it end-to-end with LeafBlox sections, sliding the brushes beneath existing gutter hangers where necessary. Sections can bend around corners, and excess length can be folded back into the gutter.
No Roof Penetration
LeafBlox sits inside the gutter. It does not require screws, nails, drilling, or fastening through the roofing material, fascia, or gutter.
LeafBlox Materials and Technical Information
Bristles
Black UV-treated / UV-stabilized polypropylene.
Core
Galvanized steel wire.
Maintenance
Remove sections as needed, shake or brush them clean, clean the gutter, and reinstall.
LeafBlox and Winter Conditions
The black polypropylene bristles can absorb solar heat on sunny days, which may help accelerate localized melting of snow and ice in the gutter. LeafBlox is also compatible with common gutter heater and de-icing cable applications. LeafBlox is gutter protection, not a rooftop snow-retention system.
