Pipe Hangers & Clamps & Hardware


Dannenbaum LLC supplies Pipe Hangers & Clamps & Hardware. We have extensive knowledge of pipe support components, including pipe clamps, beam attachments, pipe shoes, and other hardware. We can custom design and build special supports. Our team of experts will analyze the condition and custom design a pipe hanger or support to resolve special issues. Dannenbaum LLC has an a long line of products. For example we supply U-bolts, pipe clamps and risers, pipe saddles and coverings, rod hanger and assemblies, hardware, clevis hangers, beam attachments, and wall mounts. Spring supports are a type of pipe hanger.



U-bolts are versatile fasteners used to secure pipes, conduit, cables, and machinery, or U with screw threads on both ends. They have primarily been used to support pipework, pipes through which fluids and gasses pass. As such, U-bolts were measured using pipework engineering speak. A U-bolt would be described by the size of pipe it was supporting. U-bolts are also used to hold ropes together. In reality, the 40 nominal bore part bears little resemblance to the size and dimensions of the U-bolt. The nominal bore of a pipe is actually a measurement of the inside diameter of the pipe. Engineers are interested in this because they design a pipe by the amount of fluid / gas it can transport. As U-bolts are now being used by a much wider audience to clamp any kind of tubing / round bar, then a more convenient measurement system needs to be used.

Four elements uniquely define any U-bolt:

  1. Material type (for example: bright zinc-plated mild steel)
  2. Thread dimensions (for example: M12 * 50 mm)
  3. Inside diameter (for example: 50 mm – the distance between the legs)
  4. Inside height (for example: 120 mm)

Pipe Clamp

A pipe clamp is a bolted pipe attachment which clamps around the pipe to connect the pipe to the remainder of a pipe hanger assembly. In woodwork, a pipe clamp uses clamp heads produced commercially by numerous manufacturers. They are available in various diameter sizes, commonly ½”or ¾”, suited to the same diameter piping. The pipe is usually threaded on both ends. One head is fixed on the pipe by spinning it onto standard pipe threads. This head includes the screw mechanism for tightening the clamp. The other, movable, head slides onto the other end of the pipe. This head has a mechanism, often a series of movable “clutches” which allow it to slide along the pipe when setting up the clamping operation, but which lock onto the pipe when clamping pressure is applied.

Pipe clamps serve a similar purpose to bar clamps but are generally less expensive to purchase and have a versatility derived from the ability to use a variety of lengths of pipe to suit one’s needs. The same clamp heads might be switched over from a two-foot length of pipe to a twelve-foot length as the project at hand dictates. Having threads at both ends of the pipe also allows the use of pipe couplings, joining two lengths of pipe to extend the length of the clamp. In piping, a pipe clamp is a bottled attachment that clamps around the pipe. The clamps can be manufactured with black or galvanized finishes.


Clevis Hanger

A clevis hanger is a pipe attachment providing vertical adjustment, consisting of a clevis type top bolted to a formed steel bottom strap. They are recommended for the suspension of non-insulated, stationary pipelines.


 Pipe Saddle

A pipe saddle is a structure consisting of a saddle and integral base that is used to support the pipe by transmitting the load or forces to the adjacent structure.
