Overview

Service object: kit attribute generator.

Constant Summary collapse

CABLE_STRIP_DESCRIPTION =

Cable strip description.

%(TempZone Cable Fixing Strips: used for securing TempZone Electric Radiant Floor Heating Cable in place on floors at predetermined spacing, this kit includes cable strips, enables you to fix the heating cable to the floor at 3 or 4 in spacing and keeps the heating cable secured in position, uniformly positioned across the floor, while you install the floor adhesive).freeze
MEMBRANE_DESCRIPTION =

Membrane description.

%(Prodeso Uncoupling Membrane: Designed for TempZone electric floor heating cable. The polypropylene membrane ensures proper spacing, provides uncoupling and crack isolation benefits, and can be waterproofed. Its low 7/32 in profile minimizes floor height increase).freeze
