This is one of those handy little gizmos you never knew you needed before you saw it. The stainless-steel Stafford Universal Mounting Collar can be clamped onto a tube or pipe and has a countersunk, tapped hole so that things can be screwed to it; it’s a much more pleasing solution than the usual duct tape or hose clamps. It’s available in six sizes to fit up to 2-inch tube (from $11.95). Stafford Manufacturing Corp.; 800-695-5551; www.staffordmfg.com
