Splice Technologies' "RIBBON FIBER RETAINER" series fiber sleeve is designed to accommodate 2 - 12 fiber ribbon. Stock lengths are 40mm, but are also available in a new 30mm length for smaller packaging requirements. This product is constructed with an EVA meltable adhesive inner tube, a polyolefin heat shrink outer tube and either single or dual strength members. Our single strength member sleeve has an after shrink diameter of 5.1 X 4.3mm, while our dual strength member sleeve is designed to "sandwich" the ribbon thus minimizing any undue stress on the fiber while providing maximum fiber uniformity and retentivity. This option has an after shrink diameter of 5.7 X 4.9mm. This product utilizes special high temperature plastic members offering a lower cost alternative to our glass or ceramic strength member products. The entire assembly is designed to ensure that all members maintain perfect alignment during shipping, handling and shrinking. We are proud to say that all of our products are made here in the USA and most sleeves are in stock ready for immediate delivery.
