"If you own a Porsche with an interference engine, it's a pretty good idea to change the balance belt and the timing belt regularly, such as every 5 years."

Reviews
"I've got some that have lived under off road vehicles and horse trailers for years in mud, water, ozone, desert air etc. Cheaper quality clamps sometimes won't fit anything larger than about a #8 self tapping screw and even then the tab is so short the screw head won't fit well."
"I used these to run new brake lines, wiring, and fuel lines on my old Studebaker Lark."
"I bought a cheap windshield that came with plastic clamps..."
"Keeps the brake lines away from frame so dirt and stuff doesn't collect and cause problems down the road."
"I used these to attach copper-nickel brake line to the bottom of my Mazda 626 since the old attahment points were too rusty to be useful."
"I used these to "over-secure" brake line in a old vehicle that i replaced the rear brake lines in."
"I would recommend these for hard line installation only as the bands do tend to pinch pretty hard."
"Perfect for holding air lines brake lines and wires to the shell of the car just make sure you know the size of what you wanna hold down cause some of these sizes are smaller than I thought."
