REED Meter Box and Curb Box Lid Keys open many styles of meter pit lids and curb box lids. REED pentagon meter key capacities include standard waterworks pentagon bolts and plugs, as well as the large pentagon bolts made by both Mueller® and Ford®. Careful design and production ensure the REED pentagon and skeleton keys fit many brands of lids and bolts. REED meter box and curb box lid keys all have a turn and lift feature, allowing tool users to open a lid, lock onto it, and lift the lid off with a single motion. All REED meter box and curb box lid keys are made of strong, plated ductile iron to inhibit rust. NOTE: Standard (or small) pentagon bolts can be measured from a base to a point and given the dimension 27/32", or the length of one side may be measured and called a 5/8" pentagon. Large pentagon bolts measure 1 1/16" from base to tip (Mueller®) or 1 1/32" (Ford®). Some in the industry measure across a side and call these 3/4" pentagons. REED pentagon keys fit all these sizes.
