The Frook temporary truss brace and spacer tool by ken jaffers and peter stevens.

frook truss brace and spacer tool

The Frook is a reusable, temporary truss brace and spacer tool for use during the erection of roof trusses and is revolutionary in its design concept and application.

  • There Is No Other
  • Safer
  • Faster
  • More Cost Effective Way To Install Roof Trusses

Roof Truss installation is one of the most dangerous tasks encountered during the construction of a building.  Accidents which occur during the erection of roof trusses are often serious and can involve more than one person.  The risk of injury during roof truss erection should be minimised and the Frook is a tool that will help you achieve this.

The Frook is far superior in strength to other common methods used for temporary bracing of roof trusses.

The Frook reduces the risk of injury by eliminating some of the more dangerous situations that arise during the erection of roof trusses.  The unique design of the Frook and its ease of use allows for spacing corrections after roof trusses are in place.
Many roof trusses fall as workmen remove bracing in order to make spacing corrections.
The Frook helps to prevent such collapses.
When you use the Frook you eliminate the Russian Roulette type risk associated with using two hands to juggle the roof truss, the spacer and the nail gun whilst attempting to space and brace the truss into its right position, whilst also holding on.
Use of the Frook reduces the number of leads and hoses to trip over whilst hanging on to unrestrained roof trusses. Help minimise the risk of falling and serious injury. Help minimise the incidence of injury litigation. Help reduce insurance premiums.

Use the Frook truss brace.

Because the Frook can help you in reducing the risk of on-site accidents it is an ideal tool for use in an industry where occupational health and safety issues are increasingly important.
If one of your workers is injured whilst erecting a roof truss, are you ready for the question: "Why weren't you using the Frook"?

Frook's patented technology allows roof truss installers to have the advantage of standing roof trusses on site faster than any other similar method currently being used.
The Frooks unique design incorporates a clamp at one end and a hook at the other with a finger tip adjuster in between.
The distance between roof trusses can be preset on the Frook before erection to minimise the need for adjustment after roof truss placement.

The Frook is simple to use.
Once the first roof truss is secured you attach the starter clamps to the top and bottom chords at intervals as per Australian Standards AS4440-2004 ie. maximum 3 metres on top chord and 4 metres on bottom chord.
The Frooks for the next roof truss are then hooked through the eyelet of the first Frook and clamped onto the next roof truss when it is in position.
Conventional methods of temporary bracing often require the connection to be broken if a roof truss needs straightening.
The Frook however allows for hand adjustment whilst the roof truss is in position by the use of the secondary adjustment mechanism.
This allows for millimeter accuracy.
You then simply repeat the procedure with the following roof trusses, attaching the Frook to the previously braced roof truss to create a continuous line of secured Frooks and roof trusses.

Unlike other connectors or temporary braces the Frook can be used with varying timber width and roof truss distance.

Result: Unparalleled time savings.


Additionally there are significant cost savings to be gained by using the Frook truss brace because of the substantial reduction of crane time on the job and the elimination of temporary bracing materials and associated preparation works.

When the framework is in place and secure, you simply remove the Frooks and take them to the next job.

The Frook comes in two standard sizes, 600mm and 900mm. The built in adjustment mechanisms and combination use will cater for any spacing from 330 mm to 950mm.

Result is:
  1. Savings on crane time costs,
  2. Savings on other bracing materials - not needed,
  3. Savings on labour costs.
  4. Frook saves $$$$$$ - It's that simple.

Bill's comments

I think the guys have a good and useful product here.
It looks to be well thought out and it should be fairly cost effective, because it appears to be manufactured out of an existing line of carpenter's hand cramps.

I agree with the points that they make about safety, ease of use and maybe the cost savings, but what would sell this system to me is the ability to set the spacings beforehand so that consistency and accuracy is guaranteed.
I've seen too many jobs where the trusses are less than perfect.  To work correctly roof trusses have to be fixed in the right positions.  Straight and plumb!

There's no doubt also the the use of odds and sods of timber for temporary bracing is a real pain in the bum.  The overhanging ends get in the way of the next trusses to be fixed.
A lot of jobs I see now, there are actually no timber battens used, (either roof or ceiling), they are all steel, so we don't have a plentiful supply of cheap bracing timber on the site anyway!

Best of luck with it Ken and Peter!

Just in case you have read a few of these pages and you think that my comments are a bit biased in favour of the inventions, well.... you are right.  Why would I bother putting something here if I don't think it is any good?  There are heaps of websites that promote crap for money if that's what you want.
