The K100-75 adjustable drain also known as a telescoping tailpiece or telescoping standpipe enables manufacturers and professionals to install code compliant adjustable height sinks and lavatories.  The interior wall of the K100-75 is smooth and installs vertically, so there is no possibility to create a secondary trap or otherwise collect waste water within the assembly.  This telescoping drain is ideal for hospital decontamination sinks, adjustable height sinks and vanities, adjustable height shampoo sinks, and adjustable height hand wash stations.

When carefully installed so the drain is vertically plumb and moves in the same plane as the fixture without binding, this system will provide many years of service.  This product has proven its durability after 15 years of successful installation and used in adjustable height commercial shampoo fixtures.
