Yes. The multidiameter clamp Abranyl® ABT allows the pipe to expand and contract freely. Due to our patented closing system the pipes are not secured with a screw and nut, and therefore can allow for movement. The ABT is also made from a modified nylon that is more flexible compared to materials such as PVC and also perform well against temperature changes.

Our ABT has also been KIWA certified for plastic water pipes, where they have been tested at +90°C

After pushing your pipe inside the smart clamp you will hear a snapping noise and the dented closing of the clamp will remain closed.

We always work on outside diameter of the pipe. Just measure the outside diameter of your pipe, tube or conduit and check its diameter. Then select the smart clamp reference that fits to your pipe size. You will find our measures in our leaflet or the product pages of this site.

Our UL rated Smart Clamps are made of high technical nylon ensuring a safe installation of electrical pipes and conduits. Our smart clamps have a high load capacity up to 370 lbs which is far enough to hold any type of installation of electrical pipes and conduits. However, each clamp size has its own capacity and we have a chart to show the clamp’ weight bearing capacity. This chart can be found in the spec sheets of each clamp.

The Smart Clamp range is compatible with most of the gas nailers available although for the best performance and effortless installation we recommend you use the powerful, lightweight and ergonomic FORCE ONE.

The Smart Clamps are made of Nylon PA6, and can often be used where stainless steel is required. A full list of the properties of the clamps can be found in our leaflet.

These UL certificates and other technical documents can be downloaded in our download center.

Yes, the Smart Clamp can securely be installed outdoors and its performance is guaranteed during its lifecycle. The SSC, STC, and ABT are approved with UV certificates which be downloaded here. Our clamps have been tested following the ISO4892 norm. If you need more details please contact us at

Yes, our clamps are UL 2043 certified as indicated in the file E480214 and the UL 2043 norm (Fire Test for Heat and Visible Smoke Release for Discrete Products and Their Accessories Installed in Air-Handling Spaces). The norm confirms that our clamps are suitable for use in Air-Handling Spaces in accordance with Section 300.22(C) and (D) of the NEC" for devices constructed of polymeric materials.

A hammer drill is recommended when drilling into concrete. The hammering motion helps break down the concrete while the drill rotation creates the hole.

Concrete screws may also be called concrete anchors, concrete fasteners, or by the brand name Tapcon screws.

Concrete screws are a quick and easy way of fastening to concrete, they do not require hammering like other fasteners. All you need to do is drill a hole, clean it out, and drive in the screw, which we recommend doing with an impact wrench.

The drill hole depth and diameter will depend on the size of the concrete screw being used. Please, make sure to consult the technical data sheet.

All concrete screws can be removed if necessary. This is perfect for when a project changes and fixtures need to be moved.

No. Concrete screws are directly screwed into the pre-drilled hole. 

If you still have any queries then please get in touch with us and we will be more than happy to assist you.
