1. Features of CMR-DA Type Fenders 1.1 High energy absorption and low reaction force. CMR-DA fenders are new generation of V fenders , with 3-3.5%increased energy absorption. That is: Application of the CMR-DA super arch fender can reduce product height and save project cost. The following is the performance comparison of these two kinds of fenders.

1.2 Reasonable Structure and long service time
The special structure design of the CMR-DA fender greatly improved the stress concentration under compression deflection which prolong its service time a lot.
1.3 Front panel was set on the top to protect the fender and reduce the surface pressure. With front panel set on the top, the surface pressure is greatly reduced, and also the use o the ace pad reduce the friction coefficient with ships, therefore increase the adaptability for shearing force at ship berthing. Example of CMR-DA fender application: (1) NO pre-built-in steel plate and face pad on the top. (2)Applicable for small docks and ships in abnormal shapes. (3)Normally applied for small barges and fishing vessel.
1.4 Easy for replacement Because the CMR-DA fender has the same bolt pitch as the V type, it can be easily used to replace the V type fender so as to obtain higher performance.

5. CMR-DAF Type Fender
5.1 Feature CMR-DAF Fenders is to install pre-built-in top part of CMR-DA fender, it can be connected with face pad directly Or connect with front panel coved with face panel, so as to reduce the friction coefficient between ships and fenders and prolong the fender service life. There are there structure forms: two bevel ends, two straight ends, one bevel end and one straight end.

6. CMR-C Type Fender CMR-C type fender is produced by adoption of advanced material and procedure to cohere 20-30 thickness UHMW pad directly to the fender which maintain CMR-C fender performance so as to reduce the friction coefficient of fender against ships and also reduce project cost.China Arch Rubber Fender manufacturers website:http://www.chinamarinerubber.com/rubber-fender/
