Using your Bessey Telescopic Drywall Support ST125 is easy. First, for a rough pre - setting, use the telescoping and quickly lock the inner pipe to get close to the desired length. Then, turn the support at the foam grip to do the final clamping. These supports are great for drywall installation on flat surfaces or slopes. The contact surfaces can swivel from - 45° to + 45°, so you can use them on angled areas. Remember, the maximum load capacity is 150 kg when the telescopic rod is fully retracted, but this depends on the size of the support and the length you're using. When not in use, store them in a dry place. Wipe the steel pipes and contact surfaces regularly to keep them in good condition. And because they're GS - certified, you can trust in their quality and safety.
