• It is made of highly durable steel material. So it has a semi-permanent life. (A shutter is made of stainless material) 

• It has an alien substance prevention device to effectively block off alien substances coming to the finger and thereby improves the durability of a bridge. 

• Its structure connects from finger to finger. It is relatively less affected by noise and impacts. 

• A completed product shipped from the factory. Excellent quality.

• An alien substance prevention device is combined with the sub finger plate. 

• When the bridge is contracted, the finger bottom and the sliding effect cause it move downward. 

• When the bridge is extended, the original shape is recovered between each finger. (Elastomeric rubber material)

※ 1. The above dimensions are standard dimensions. They are subject to change depending on the site conditions. 

2. A curved bridge may cause the finger shape/angle to vary depending on the direction of expansion joint or rotation.
