Q: What temperatures can the Duraclamp^® withstand?

A: The Duraclamp^® can be exposed to temperatures up to 212º Fahrenheit (100º Celsius) without any effect on its' mechanical or physical properties. Clamps that are exposed to higher temperatures for long periods of time will begin to soften and lose their structural integrity.

Q: Are there any metal finishing chemicals that can attack and damage the Duraclamp^®?

A: Duraclamps^® are made from a high-tech, fiberglass filled, thermoplastic impervious to all anodizing and plating chemicals. Brite dip solutions can discolor the Duraclamp^® but will not effect its' structural integrity or usefulness.

Q: What is the best method to rack an extremely heavy load with Duraclamps^®?

If the load is extremely heavy, utilize a rack with a horizontal cross piece supporting the load. The clamp can then be used to achieve a positive electrical connection.

Q: Can Duraclamps^® be utilized to rack odd shapes and sizes during the finishing process?

A: Most definitely. The placement flexibility of the Duraclamp^® is one of its' many strengths. However, care should be taken to insure that the frame and screw portions are properly aligned to avoid placing undue stresses on the Duraclamp^®

Q: What is the best method to tighten and loosen Duraclamps^®?

The Duraclamps^® are designed to be tightened to a torque of 50 to 60 inch pounds by hand or by our factory set Duralok™ torque wrenches only. This range is more than adequate to secure extrusions, sheets and brake metals.

Q: Will the Duraclamp^® resin have any negative effect on the finishing baths or wastestream?

No. The Duraclamp^® is electrically and chemically inert. It will not absorb or expel any chemicals or metals in your baths and wastestreams and it will not thieve any electricity from the finishing process.

Q: What size and style Duraclamp^® would be best for our operation?

A: There are many factors that must be considered when determining the right Duraclamp® for your facility:

1. Size and shape of piece to be finished.
2. Size of your finishing baths.
3. Size of your standard spline bar.
4. Customer requirements regarding rack marks.

We recommend that you refer to the links on "Duraclamp^® Specifications" and "Special Feature Guide" to learn more about Duraclamp^® options.

Q: What are the advantages of using a Duraclamp^® with an alumina oxide tip?

A: Anodizers and platers order Duraclamps^® with alumina oxide tips for two primary reasons:

1. The tips only make a "pinpoint" rack mark leaving more useable metal to satisfy production and/or customer demands.
2. The tips tend to dig into the spline bar and the work piece therefore creating a more secure load.

Remember also that alumina oxide is actually a "diamond hard" ceramic material. It is uniquely suited for "2-Step" anodizers that cannot utilize titanium tips because of the halo mark they leave on the work piece at the contact point.
