Thermoplastic Planter Liners - High-impact polystyrene - custom sizes
Thermoplastic Planter Liners   

General-use thermoformed liners are made from >60% recycled ABS, approx. 3/16" thick. UV inhibitors are added to the material, but for applications where they will be exposed to direct sun, field painting is recommended. All liners are created to a +/- .125" tolerance.  Liner thickness will vary slightly from the ends to the center, and walls may flex outwards on longer liners. Drains can be installed by installer in any location your application requires.

The liners are molded to order, typically with a 3-5 week lead time.

Available in 115 sizes from 24"-72" L (every 6") x 9"-33" W (every 3") x 8"-17" D, to work with most planter projects.  Flanges can be trimmed by approx. 1" in each dimension or cut up to 3" longer.  (See dimensional details below)

Planter drain kits Drain Kits - DeepStream's stock liners come with a threaded drain. Reservoir liners come with a copper drain pipe already inserted.  If you want to control the overflow water, order a hose kit, which includes hose barb and valve.  This allows you to direct planter overflow to a drain or container.

Thermoplastic-molded and custom-welded liners can be drilled for drainage underneath, or can be retrofitted for a hose kit by drilling and inserting a 90-degree hose barb, to which you attach the hose and valve.  A brass insert is available for connecting a garden hose or a pump kit to the valve.
[1/2" or 3/4" hole saw required for drain kit installation.]
