GEKO by Rothoblaas: Panel pullers and carpentry tools for precise timber installations

When assembling solid timber or timber-frame structures, ensuring the correct fit between timber elements is a process that requires care and attention: a poorly closed joint can compromise the alignment, airtightness and stability of the entire wall.

That’s why industry professionals rely on specialised carpentry tools – equipment that offers strength, precision and safety during installation.

Among these, Rothoblaas GEKO panel pullers provide a reliable solution for tightening and positioning timber elements, from large CLT panels to lightweight frames.

The range includes three versions – GEKO MINI, GEKO and GEKO MAXI – covering all on-site applications, from high-precision adjustments to heavy load handling.

The principle: Controlled traction and respect for the material

The panel puller is a mechanical device that generates an adjustable pulling force between two timber elements, ensuring a gradual and uniform fit.
Unlike traditional levers or jacks, GEKO systems apply force without impact or deformation, preserving the integrity of the timber surface and the geometry of the joint.

This approach makes it possible to:

• compensate for prefabrication size tolerances;

• simplify the installation of large panels;

• ensure stable and repeatable tightening;

• improve both the safety and quality of the assembly.

GEKO MAXI – Panel puller for large structural elements

GEKO MAXI is the high-performance version of the range, designed for use with large or heavy panels, such as CLT walls or solid timber floors.

Main characteristics:

• traction force up to 7 tonnes;

• variable performance depending on the number and length of the screws;

• suitable for large elements, including vertical installations.

Its high-strength steel structure and even load distribution allow safe operation even on multi-storey panels.
It is an essential tool for carpenters working on large-scale timber constructions, where precision and power must go hand in hand.

GEKO: The versatile panel puller for timber construction

The standard version of GEKO is designed for most on-site applications, from the assembly of load-bearing walls to the closure of flush joints between panels or floors.

Thanks to its reversible screw system, the panel puller can either push or pull panels into perfect alignment, always maintaining full control of the applied force.
It is a simple yet precise mechanical tool, ideal for small carpentry workshops and large companies alike working with CLT and timber frame systems.

GEKO MINI: Compact, adjustable, universal

GEKO MINI is the most compact panel puller in the range, designed for everyday applications and precision works: timber frame constructions, interiors, stairs, doors and windows.

Its main features:

• compact size and lightweight body, perfect for confined spaces;

• full body rotation, allowing work in any direction, even on uneven surfaces or those with complex geometries;

• compatibility with the CRICKET ratchet, which serves as a traction handle.

One CRICKET is sufficient to install all GEKO MINI panel pullers required for a project, thus simplifying site logistics and cutting costs.
The ratchet is ordered separately, making the system modular and easy to configure.

A modular system and operational safety: When carpenters design for carpenters

The GEKO range is designed as a modular system of carpentry tools for timber assembly.
Every component – from the main body to the screws – is designed to guarantee:

• stability during traction, without unwanted rotation;

• ergonomics and comfort of use, thanks to the optimised grips;

• utmost safety, with tested materials.

Routine maintenance is limited to lubrication of the moving parts and a visual inspection of the screws and ratchet prior to each use.

Whether working with solid timber walls, prefabricated elements or lightweight frames, proper panel tightening directly affects surface stability and flatness, airtightness, soundproofing, joint durability and long-term structural integrity.

With GEKO panel pullers, panel joining becomes a measurable, controlled process, turning a manual task into a precise technical procedure.

GEKO, GEKO MINI and GEKO MAXI represent the pinnacle of carpentry tools for timber panel tightening.
Each version meets a specific requirement – from manoeuvrability in precision works to the power needed for large structural panels – guaranteeing accuracy, reliability and durability.
