BHOgart double bolt clamps are used on various BHOgart products
The double bolt clamps feature a bolt on each side of the clamp. This allows the clamps to evenly distribute the pressure between two bolts instead of one. This makes it much safer, and more reliable with maintaining a seal. The clamps use brass bolts to reduce loosening due to temperature swelling and contracting. Brass also reduces the chance of creating a spark, making the unit even safer.
