H-clamp Support

Problems with your H-clamp?

The H-clamp is designed and built to be as simple as possible to use, to last a lifetime and to withstand everything but the most severe abuse. As a result, problems with H-clamps are extremely rare and can always be sorted out, usually very quickly and easily.

Nevertheless, if you ever experience any difficulties with your H-clamp and the manual doesn't seem to help, please contact us.

Please also contact us if you have an idea for using the H-clamp that is a little out of the ordinary and you would like some advice before trying it out or if you're at all unsure about how it works with any particluar microphone or instrument.

If you've lost your manual or it isn't easily to hand, you can download a pdf copy by clicking the link:

You may also find useful answers and hints in the   Live Applications   and   Studio Applications   sections of the   Information   page.

Reported Issues

We don't have an FAQ section because there really aren't any questions that arise frequently. However, occasionally the H-clamp may seem not to be working perfectly. Please don't hesitate to contact us if you have the slightest suspicion all is not well and please check the Reported Issues below in case it's something that other customers may also have experienced.

• Synthetic rubber 'O'-rings on underside of Top Disc
• Cross-Threaded

Top disk 'O'-rings become unseated from their grooves

In normal use, it is very unlikely that the 'o'-rings will come out of their grooves. The grooves have a slight lip to retain the 'o'-rings under all but the most exceptional circumstances. Indeed, it is difficult to remove the 'o'-rings, except by picking at the cut edge where it meets the slot in the top disk.

Problems may however occur if the H-clamp is used incorrectly, for example, by attaching it with the slotted side of the top disk over the instrument. When the clamp is tightened, the cut ends of the 'o'-rings may be squeezed so that they protrude into the disk's slot. When the clamp is then loosened for removal and slipped off the instrument, the 'o'-rings may be dragged out of their grooves.

Alternatively, the ends of the 'o'-rings that had been squeezed out into the slot may not retract when the pressure is released. They may then become 'snagged', for example on the boom when it is swung into the slot, causing the 'o'-rings to be lifted out of their grooves.

In the event an 'o'-ring becomes unseated, it can be reseated easily by simply pressing it back into the groove.'O'-rings that have become detached entirely can also be refitted in this way but if they do not appear to be long enough to stretch all the way round the disk, from one side of the slot to the other, the best approach is to start pressing it into the groove at one edge of the slot and stretch it gently while pressing it into the groove around the disk, gauging how much stretch will be necessary for it to reach the edge on the other side of the slot.
