ADJUSTABLE SPRAY WALL 


SLAB WALL
ON LEMUR FRAME.


Slab Wall represents the ultimate adjustable climbing wall for gyms that refuse compromise. No app dependency, no locked-in systems — just complete freedom to adjust angles (+10–40°), set your own spray problems, and evolve your wall infinitely. 

The first truly adjustable spray wall that puts creative control entirely in your hands.

Adjustable Spray Wall Without Limits

Adjust the angle. Spray the wall. Climb.

No download. No routing algorithms. No waiting for problems to load. Just you, a wall that shifts, and infinite possibilities. The Slab Wall isn't a system — it's a blank canvas. Every angle is new. Every session, climbers discover moves they couldn't do yesterday on a traditional fixed spray wall.


Simple. Adjustable. Addictive

Adjust. Spray. Repeat.


 HOW IT WORKS 

The Slab Wall adjustable spray wall works in three simple steps:

  • Pick your angle on the Lemur frame (+10–40°)
  • 8 standard sizes, from 16×12 ft and up
  • Adjust freely to shift difficulty and discover new movement. 
  • Set your own spray problems using holds of your choice.

No routing algorithm, no external dependency. Change it tomorrow — an adjustable climbing wall means infinite reconfiguration without rebuilding.



 WHAT SETS IT APART - THE ADJUSTABLE SPRAY WALL REIMAGINED  

Complete freedom to set, spray, or blend both. One climbing frame. Infinite configurations. Climbers discover new movement possibilities as the wall angle shifts — beginner-friendly at shallow angles, brutally hard at 40°.

  • Adjustable from slab to fully overhanging
  • Spray or boulder — your choice, your rules
  • Different difficulty levels from one angle shift
  • Design holds and layouts without technical constraints
  • Perfect for gyms wanting full creative control
  • Foundation for 100% adjustable facilities

​

 ORIGINS  

Born from the idea that walls don't have limits.

Lemur Design, founded in 2018 by aerospace engineers, built adjustable climbing frames for standardized connected boards. But climbers and gyms asked: "What if we could set it ourselves — with complete creative control?" The answer was the Slab Wall, launched in 2022 as the first truly adjustable spray wall. No app. No system. Pure climbing freedom.

 2018

  Lemur Design founded in Montreal by aerospace engineers. The first frame built to adapt — not to one system, but to all of them. Infrastructure before ideology.

 THE FOUNDING 

 

2022

Slab Wall launched: the adjustable frame reimagined as a canvas for gym creativity and climber progression.

 FREEDOM 

 WHY CHOOSE AN ADJUSTABLE CLIMBING WALL 

​

Install once. Evolve forever.  Without Rebuilding

A fixed spray wall locks you into one difficulty profile. An adjustable climbing wall opens up infinite possibilities. Change the angle. Shift the difficulty. Refresh the spray problems — all without rebuilding. The Slab Wall adjustable frame grows with your climbers. One installation. Multiple configurations. Multiple futures.

THINK BIGGER - A COMPLETE TRAINING SPACE

A Slab Wall is just one piece.


An adjustable wall comes into its own inside a space designed for progress: a connected wall, a spray wall, a Güllich pan, a conditioning zone. That's a Training Room — and it's exactly what Lemur builds, from first sketch to opening day.

01 What makes the Slab Wall different from other adjustable walls?

The Slab Wall is pure freedom. No locked-in system. No app dependency. You control the angle, the holds, the layout, the difficulty. It is built for gyms and climbers who want to set their own problems and evolve their space without third-party constraints.

02 Can I use it as both a spray wall and a boulder wall?

Exactly. The Slab Wall is both. Spray freely at 10°. Set defined problems at 20°. Go full power at 40°. One frame, infinite configurations. Your gym controls the narrative — change it whenever you want.

03  Do I need to buy holds from Lemur?

No. You're free to source holds wherever you want. But we can also supply the full package — holds, hardware, flooring coordination — through our reseller network. One delivery. One contact. Your choice.

04 What sizes and angles are available?

The Slab Wall comes in 8 standard sizes, from 16×12 ft and up, and adjusts from +10° (slab) to 40° (overhang) in smooth increments. The Lemur team sizes your wall during the feasibility study, based on your space and vision.
