Metal Buildings
Pre-engineered and post-frame metal buildings often use large, high-capacity gutters that benefit from a larger brush diameter.

LeafBlox Gutter Guards for Commercial Metal Buildings
Larger metal-building gutters can require a larger brush diameter than standard residential gutters. LeafBlox brush-style protection sits inside the gutter, fills the available space with bristles, helps block leaves and larger debris, and allows rainwater to move toward the downspout.
Common Metal Building Gutter Fit
The comparison below shows how different brush diameters fit within a common metal-building gutter profile. The brush is intentionally larger than some of the gutter dimensions so the bristles conform to the gutter shape and fill the available space.
Why Brush Diameter Matters
LeafBlox is designed to sit directly inside the gutter rather than spanning across the top like a screen or rigid cover. For the system to work as intended, the bristles should occupy the gutter cavity and conform to its shape.
In many commercial metal-building gutters, a brush diameter can be larger than the narrowest gutter dimension. The flexible bristles compress and spread within the gutter while the central wire core remains positioned inside the channel.
This helps keep the brush in place without drilling, screws, nails, or permanent attachment to the roof or gutter.
Where Commercial LeafBlox Is Used
Warehouses & Industrial Facilities
Large roof areas can direct substantial water volume into gutters while nearby trees contribute leaves, twigs, and other debris.
Commercial & Institutional Buildings
LeafBlox can be used where accessible, serviceable gutter protection is preferred without permanently fastening a cover to the building.
How Water Moves Through LeafBlox
Rainwater passes between the polypropylene bristles and enters the gutter below. Once inside the gutter, water continues toward the downspout in the normal direction of drainage.
The brush does not create a solid surface above the gutter. Its purpose is to occupy the gutter opening with bristles that help keep larger debris from settling into the channel while still leaving pathways for water.

LeafBlox sections are placed directly inside a clean gutter. No roof penetration or permanent fasteners are required.
When maintenance is needed, sections can be removed, cleaned, and reinstalled.
