Tamper-Proof Sleeve Anchors – How and When To Use Them

Bike racks, fences, security railings, public art installations, air conditioning cages, storage cages for propane — what do these things have in common? They all require effective security solutions to save time, money and ensure public safety. They also often require securing to materials like concrete, brick, and stone.

For security in this type of application, Loss Prevention Fasteners recommends tamper-proof sleeve anchors


Tamper-proof or security sleeve anchors are an easy-to-use adaptable masonry anchoring system. Designed to be used on a range of materials and for a variety of applications, sleeve anchors are a versatile security option. 

These sleeve anchors can be used for light or heavy-duty fastening in concrete, brick, block and any other stone-based materials. When the security head of the anchor is tightened, the body expands against the base material to create a strong connection that is able to distribute load-bearing weight.

Loss Prevention Fasteners uses an Ultra 6 lobe pin sleeve anchor in various sizes. If you’re not sure whether we carry an appropriate size for your application, see the visual below for more details on the available sizes for security sleeve anchors. This visual also offers helpful information on how to determine which size of sleeve anchor is best for your application. 


These anti-theft anchors come in either a full stainless steel version or with a stainless steel head and zinc-plated body. The stainless steel sleeve anchors are suitable for outdoor, wet environments and the zinc-plated body versions are recommended for indoor, dry environments. When deciding which version to use ensure you’re using the appropriate design for the environment where you’re applying your sleeve anchors

Although these sleeve anchors are removable, we recommend that you don’t regularly remove and re-install. Since the sleeve anchor expands in the ground once it’s installed, frequent removal will degrade its efficacy. For more information on how the sleeve anchors are installed, see the visual below.



Security sleeve anchors are appropriate for a number of applications. In public spaces, they can be used to secure benches and tables. When it comes to railings and fences they can be used to secure valuable materials and to ensure the security of railings and fences that are installed because of safety concerns. In many cities, bike racks are everywhere—including those used for municipal bike programs. Sleeve anchors can be drilled through the bike rack and into the concrete for a tamper-proof installation. They can also be used to secure directional signs or valuable plaques that are installed on concrete walls or large boulders. In residential situations, they can be used as an anti-theft option for air conditioner cages or garbage receptacles. 


With security anchors, you can confidently prevent theft and tampering and ensure safety. 

So whether you’re looking for anti-theft options for public installations or securing a residential plaque, when it comes to stone-based materials your best option is a tamper-proof sleeve anchor
