Our MDM is a pure mechanical cable closure. It was developed as a series of In-Line closures (type MVM) and Branch-Off closures (type MAM).

One closure kit consists of two symmetrical half-shells with a foamed rubber length seal fixed in the top shell.

The half moon shaped length seal is designed to be compressed between the two halves when the closure is installed, keeping it absolutely watertight.

The shells are screwed with nuts and bolts made of stainless steel. The nuts are fixed in the bottom shell, so they can not be lost.

Inside of the bottom half shell in front of each entry is a strain relief for the cable. In the middle of the branch-off bottom half shell the anchor point for the adapter to accommodate the fibre optic splice cases is located. If a copper splice is produced, this adapter is not needed.

The end caps are made of soft EPDM rubber and are conically shaped, so they fit a wide range of cable diameters. The narrow end of the end cap becomes cut at the half diameter of the cable. A double end cap set makes it possible to fit 2 cables at 1 closure entry at the same time.

After the splice work is done, the two half shells are screwed together very strongly. The body of the closure is then very solid and each entry has a round shape. Each end cap becomes flipped over its entry of the closure and gets fastened with stainless steel hose clamps.

Accessories like single or double end cap sets and length sealing sets are available.

FRIEDL developed the MKM closures to beat the old fashioned heat shrink systems at the point of technology and at the point of economy. It is succesful in both ways, because HS (hot shrinking) systems are extremely sensitive to environmental conditions during installation, therefore they high failure rates, difficulties in reopening and are not reusable.

Therefore, the FRIEDL MKM cable closures meet the fibre optic market, the copper cable market as well as the electrical/power market.
