L-Bead Installation: New and Improved

 
Posted Tue, March 24, 2015

Here at Coco Architectural Grilles and Metalcraft we are dedicated to improving our existing product line and inventing new options for contractors and architects. Our most recent project was to improve our popular L-Bead  installation option which allow for flush grille installations in plaster and drywall.

What is L-Bead?

This installation option is commonly known as a “mud-in” and we have a patent pending for our unique product. What makes ours different? We have received a lot of feedback from installers and all of our design features are inspired by their input. We have the highest level of plaster recess, our welding process prevents plaster cracking, and the core of the grille is removable, which allows for future duct work behind the grille without damaging the plaster.

The L-Bead installation option can be applied to almost any linear bar grille and perforated grilles we offer with all finishes, in aluminum, bronze and stainless steel.

Creation and Installation

Coco Metals is extremely proud that our L-Bead grilles are fabricated with material extruded in America. We fabricate these frames from a solid single piece of proprietary aluminum extrusion. The removable core grille is fastened with stainless steel threaded inserts at the bottom of the grille as well.

Manufacturing the frame with the plaster bead/flange as part of the single piece proprietary aluminum extrusion allows cost savings to the end user as fewer components and fabrication operations are required to create the finished product. The plaster bead/flange is also stronger, as it is not a secondary piece welded or mechanically fastened to a standard frame.

Our L-Beads are tack welded at the corners to prevent plaster from cracking due to expansion and/or contraction of the material. They also include pre-punched holes for quick mounting, and have recessed grooves to help capture a full 1/8” mud-recess to achieve a Level 5 Plaster Finish, which is distinctive to Coco Architectural Grilles.

The removable core feature, allows access to the duct work behind the core grille. A significant enhancement included here are the Stainless Steel Threaded Inserts. The core includes welded mounting tabs at the bottom. In lieu of a drilled/tapped hole through just 1/8” of material at the bottom of the frame, the Stainless Steel Threaded Insert is press-locked into a clear hole. This allows a lifetime of use for the removable core option as the potential for cross threading or stripping out of the holes is eliminated. A drilled and tapped hole can be damaged if installers or servicemen cross thread or strip out the mounting holes during initial install or service of the duct work behind the core grille.

Whether you are fitting for a mitered corner or curved wall, these grilles and frames can be fashioned to fit your architectural vision.

 

Finished Product

This design creates an elegant flush finish that gives the illusion that the grill was built into the wall. This feature is in high demand among our upscale residential projects.

The L-Bead installation option can be applied to linear bar grilles, decorative perforative grilles, and any other custom metal products we offer.

As we continue to improve this product, we will update this post with pictures and more information.
