This skateboard deterrent is a ball and stud designed to be installed along the edges of concrete or stone benches, walls and planters. The standard GrinderMinders are made from solid stainless steel with a brushed finish. All of our GrinderMinder shapes are priced identically.
The sleek new Hemisphere (“Hemi”), design is based on the original GrinderMinder and features a sleek lower profile “half-dome” top. Just like the original GrinderMinder, it looks great and secures well into edges of concrete or stone benches, walls and planters.
The new Cylinder GrinderMinder is another version of our original spherical design. The “Cylinder“ will give a lower, flat profile and is inserted at a 90 degree angle into the stone or concrete, rather than at an angle. The stem of the “Cylinder“ is identical to our original GrinderMinder, so that it will provide the same stability and resistance to vandalism.
These skateboard deterrents are designed for either round or flat-topped handrails. They are made from aluminum and are specially coated with a paintable surface, if the customer wishes to match the deterrents to the handrail. They are supplied with self-drilling and threading stainless steel screws. The standard finish is silver, if left unpainted.
Important – Calculating the outside diameter measurement of your round handrail:
Accurately measuring the outside diameter (O.D.) of your round handrail is key to ordering the correct size Handrail Minder. We match the inside diameter (I.D.) of our Handrail Minders to the O.D. of your handrail.

These deterrents are designed to be used on metal or wood handrails and benches. They are the standard 1” GrinderMinder stainless steel ball, black oxide finished, with a threaded hole on the underside that will accept a bolt. Customer will drill a hole through the rail or bench surface and bolt these pieces on from the underside. Bolts are sold separately to the customer’s specified length. Other materials and finishes can be used for custom pieces.
IMPORTANT NOTE: GrinderMinders should never be used in the path of pedestrians
