The PT-2 system grate frame and grate incorporate a 2-bolt lockdown design firmly securing the grate to the frame (with optional center toggle locking device).

Design Flexibility and Customization

Design flexibility and customization of the EconoDrain and EconoDrain PT-2 Systems Is a major contributor to its uniqueness in the field of area drainage solutions.

The design team at MultiDrain Systems, Inc. is available to assist in establishing all necessary requirements for a custom or partially custom system resulting from changes in standard size, finish and slope of trench drain components.

EPS Trench Forms

• Standard trench slope of 0.5% [1/2” of fall per eight (8) feet of run].
• Standard trench widths of 8” and 12”.
• Standard EPS form length is 8’
• Custom slopes, widths, depths and length of runs are available.
• Interlocking EPS forms provide additional stability of system during concrete pouring operations.
• Standard trench geometry includes a hydraulically efficient radius bottom or an optional square bottom.
• EPS Intersection kits make Tee’s and Ell’s fast and easy to install.
• Pigmented form release helps assure overall and complete coverage.
• Design facilitates easy and quick form stripping.
• Deep channel form stabilization assures stability.
• Pipe installation is quick and easy at outfall or outlet locations. Horizontal, vertical or in-between pipe outlets can be made anywhere along the EPS form length unlike other fixed outlet point systems requiring difficult and expensive stubbing and fabrication to match pipe to a fixed point.
• EPS forms are easily field cut or mitered by the contractor to fit project specifications or make field alterations which are necessary from time to time.

Grate Frame

• Standard finish is black polyester powder coating. Galvanized and stainless steel are optional.
• Frame Rails are pre-drilled and extension nut and anchor affixed with temporary bolts for two point grate bolt down.
• Grate Frames with factory welded spacer rods minimizing site assembly and setup. Spacer rods assure accurate frame width dimension and co-planar geometry.
• Field assembled Steel Rails and Bolt-In-Place Spacer Bars, assure accurate frame width dimensions and co-planner geometry.
• Anchor stands facilitate quick setup, permits easy grade adjustments, resist flotation forces and secures the grate frame, in addition to weld studs, into the surrounding concrete.
• Standard grate frame length is 8’.
• Frames are easily field cut by the contractor to fit project specifications or make field alterations which are necessary from time to time.
• Interlocking Frame Brackets provide alignment, accuracy and ease of installation.
• Miters are easily field cut.

Gratings

• Standard grates are Extra Heavy Duty PT-2, ductile iron grates capable of FAA AC 150 5320-6D Part 5 Appendix 3 load conditions (AASHTO M306, HS25)
• Grate finish is Uncoated, optional hot dip galvanized.
• The grate is secured to the frame by a 2-bolt lockdown pattern or optional center toggle and lockdown pattern or optional center toggle and locking device.

Catch Basins

• Both In-Line and square catch basins available providing a complete system.
• Catch Basins install using same procedures and materials as the trench drain.
• Catch Basin debris strainers are an available option.

SYSTEM CHARACTERISTICS

Versatile

• Available in Standard and Custom trench widths, depths and slopes.
• Catch Basins available for complete system.
• Continually sloped trench runs from 288’ up to 320’ are achievable. A center catch basin layout effectively doubles this distance.

Fast

• 8’ Interlocking EPS forms enhance stability and speed installation.
• Grate frame anchor stands provide quick easy grade adjustments.
• EPS form design installs and strips quickly after the concrete pour.
• EconoDrain PT-2 can be installed in a fraction of the time required to install conventional form-and-pour trenches or pre-cast polymer concrete trench systems.
• Unlike other systems — EconoDrain PT-2 installs in one pour.

Simple

• Only 3 components — EPS Forms, Grate Frame & Grate
• No special tools or installation devices required.
• Outlet connections at any angle.

Accurate

• Patented rebar installation/leveling system
• Welded Grate Frame spacers
• Bolt-In-Place Spacer Bars
• Pre-sloped interlocking forms
• Deep channel form stabilization.

Economical

• Cost efficiency realized in purchase cost and installation labor and time.

Robust

• EconoDrain PT-2 is always installed with a grate frame thus eliminating surface spall and load impact damage experienced with polymer concrete inlay channel layouts.
• EconoDrain PT-2 standard grate is FAA Rated, AASHTO HS25.
