What NCR wrote, in their words
NCR's category write-up for K-Guard is nearly word-for-word what they wrote for LeafGuard, with only the reputation and durability scores differing — see our sources.
Price w/ Installation — 3/5.
“Price is dependent on the commissioned sales representative.”
Effective Protection Coefficient — 2/5.
“K Guard is relatively poor due to the lack of surface tension effectiveness in low velocity rains. Debris is dragged into the gutter.”
Industry Reputation — 3/5.
“This product was developed over 35 years ago by a seamless gutter machine company and was re-invented by another seamless gutter machine company as K-Guard and also Gutter Guard... using the reverse curve technology that was patented in 1908 by George Cassens.”
Strength — 4/5.
“The strength of this system is fairly decent compared to thin sheet metal systems, but to clean the system one must either pull down the bottom half and bend back or lift the top and bend back.”
Water Throughput — 2/5.
“In heavy rains, over-shooting will occur. There is no way that surface tension can roll the water in the open slot.”
Durability — 2/5.
“K Guard is fairly durable. With metal thickness of about 0.27".”— NCR Consumer Advocacy Group, archived December 20, 2017
