The MCF Bolt-On Balcony, “B.O.B,” is a 100% extruded aluminum prefabricated balcony that ships fully welded and assembled, ready to bolt onto the building. Each unit arrives as a single piece with the decking, frame, and railing attachment points already built. Your crew bolts it to the structure and drops in the railing. That is the entire installation.
The overhead tieback rod support system eliminates the need for structural cantilevers or penetrations through the building envelope. The knife plate attachment through-bolts to LVL posts behind the sheathing. No waterproofing membrane is compromised. No structural cantilever is required.
For general contractors building multifamily and mixed-use projects, this system reduces the balcony scope from weeks of framing, waterproofing, and finish work to days of bolt-on installation. The schedule savings alone justify the conversation.
The aluminum plank decking is installed at 1/8" per foot slope away from the building for positive drainage. Non-slip V-grooves at 1" on center provide traction in wet conditions. The decking is welded directly to the framework, so there are no fastener penetrations, no gaps for debris, and no separate decking material to source or install.

Traditional vertical picket infill with 5/8" square tube pickets. Clean, durable, and cost-effective. The most specified option for multifamily balconies where code compliance and budget alignment are the priority.
Frameless glass panels with D-clamp hardware for a clean, modern aesthetic. Tempered laminated glass provides safety, sound attenuation, and unobstructed views. Specified for premium multifamily and hospitality projects.
Prefabricated mesh panels in aluminum frames for an industrial and contemporary look. Wire mesh provides visibility, airflow, and a distinctive aesthetic that pairs well with modern and urban architectural styles.
Ships fully welded and assembled. Your crew bolts it on and drops in the railing. No welders, no hot work permits, no fabrication tent on the job site.
The tieback rod support system and knife plate attachment mean zero penetration through the waterproofing membrane. Eliminates the #1 source of balcony warranty callbacks.
Replaces weeks of balcony framing, sheathing, waterproofing, and finish work with days of bolt-on installation. Removes the balcony from your critical path.
Designed for vertical stacking on multi-story buildings. Stacked balcony detail and engineering available for projects with vertically aligned units across multiple floors.
Each unit is crane-set and secured by a three-person field crew. Units arrive fully assembled, so the crew is bolting and connecting, not fabricating. Furnish-only option lets you use your own crane and labor.
100% aluminum construction means no painting, no rust treatment, no wood rot, no sealant reapplication. Powder coat finish is the final finish. Maintenance cost over the building lifecycle is effectively zero.
