Speaker Wall Mounts B-Tech BT77 Ultragrip Pro

I'm selling these completely unused wall mounts. I got them from Richer Sounds for 60 euros and haven't used them. The box is opened but nothing has been taken out of the box.

They can hold speakers that weigh up to 25kg (55lbs).

They weigh 3kg themselves.

This is from the Richer Sounds website:

The B-Tech BT77 Ultragrip Pro, side-clamp speaker wall mount makes a stylish and practical choice.

With its side-clamping system, the BT77 is ideal for speakers with curved front baffles. It's also ideal for when conventional brackets spoil the grill, badge or even drive unit or port. High friction pads grip the speaker strongly enough for them not to need additional bolts or screws; keeping your speakers undamaged.

With a face plate covering the wall fixings, the BT77 boasts a clean and modern design. Furthermore, just one lock nut secures both tilt and swivel functions, making it easy to adjust to exactly the right angle.

Coming complete with wall fixings, the BT77 makes an ideal choice for wall mounting your speakers.
