With the Linkstar L-Bracket BSH-2 you can, in combination with two light stands and a cross beam, build a complete backdrop system suitable for two backdrops. This set can also be used for expanding an existing backdrop system.
The copper pin is 53 mm long and has a diameter of 10 mm. The maximum diameter of the tube the clamp can be attached to is 35 mm. The distance from the pin to the tube is 66 mm. The clamp is fixed with a screw.
The copper pin can be exchanged with spigots (optional), so you can place extra lamps on this bracket. The clamp part is equipped with rubber so your stand won't damage.
