Company Profile

We hold several patents on our innovative Roll-Up/Lock-Down Curtain Systems and our patented structural FlareTube Products.  We provide top quality wire products such as S-Hooks (Extension Hangers) Zig-Zag Wire and Sod Staples at reasonable and competitive prices.

Roll-Up/Lock-Down Curtain Systems fit any "Straight" or "Curved" wall (Gutter Connect or Free Standing) Structures.  Since we sell in 4' increments we can fit your needs and budget with our extensive line of Curtain Operators, both manual and electric.  Many customers retrofit existing curtain systems with manual operators to insure better and safer opening for their employees.  Electric operators canprovide a fully automated Curtain System that can't be beat.

Roll-Bar Cap makes upgrading your old system to a Roll-Up/Lock-Down side-wall a snap.  Use it to clasp single or multi layers of curtain materials against any standard 1.315" OD pipe to allow tension to be applied in either rolling direction.  Fits most existing swaged pipe so you can throw away those pesky plastic clips forever.  Installs with self drilling Tek screws!

Low Voltage Motors and Controllers (24 Volt) provide a viable alternative to Gear Box and Tube Motors.  Our Low Voltage motors come in 40, 60, 80, 88 and 148 NM for great curtain rolling power.  Controllers output 24 volts OR the can be powered from a 24 volt battery source.  We also offer Computer Interface Boxes to allow you to convert to our Low Voltage Motors while continuing to use your Vent Controller.  All are designed for greenhouses that only have low voltage sources available.

Our Mission

Our name belies what we strive to do--"ADVANCE" the development of our products and provide new "ALTERNATIVES" to old problems, all-the-while, improving on many of the products we provide.
