Description
Keep water moving and maintenance low. Shur Flo’s 4-ft perforated aluminum panels slip under the shingle edge and fasten to the gutter lip to block leaves, needles, and shingle grit while maintaining high flow. Choose mill finish (5SF4 for 5" gutters, 6SF4 for 6") or a sleek black finish (5SF4BL, 6SF4BL) to match the system. The low-profile design disappears from the curb, resists corrosion, and stands up to heat, cold, and heavy rain—so your gutters do their job without constant cleaning.

FAQs
Q: Will these panels fit my gutter size and style?
A: Compatible with standard K-style systems: 5" (5SF4/5SF4BL) and 6" (6SF4/6SF4BL). Verify roof edge/drip-edge details on specialty installs.
Q: Do they install under shingles or onto the front lip?
A: Most installs slide the rear edge under the shingle/drip edge and fasten to the front gutter lip or fascia with exterior-rated screws/rivets.
Q: Can the perforations handle heavy rain without overflow?
A: The fine perforation pattern sheds leaves while maintaining water throughput. Proper gutter pitch, clean troughs, and adequate downspout capacity are key.
Q: What maintenance is required after installation?
A: Inspect seasonally. Brush or blow off surface debris and ensure downspouts are clear; aluminum panels won’t rust but staying clear maximizes flow.
