Our innovative design has been created for use in the construction industry, on commercial build projects. The team at JMAC Safety Systems identified a gap in the market for this product last year, and since then have spent time trialling and testing the design to ensure, like we do with the rest of our products, we’re offering the best on the market.

The Extendable Leg


The JMAC Safety Systems Extendable Leg can be used for traditional build houses, 1.8 platform, timber frame builds, 2.0m platform, or commercial buildings typically 2.4m – 3.0m platform. One leg fits all.

The extendable leg is installed with the use of a podium for any height over 2.0m. Our specialist installation teams will attend site and provide a detailed and thorough step by step installation guide.

Due to the durability and increased strength of the extendable leg, the working load remains at 2.0kn (200kg) per m2, even when the platform is erected at 3.0m

As with the standard legs, the extendable legs can be manufactured with your company branding and colours.

Due to the increased strength of the leg, the shock absorbing supersock was developed to allow impact and energy to be absorbed, diverting the initial impact away from the surface of the system.

I’d like a quotation for your Macdeck system/products, what are my options?

Our bespoke quotes are based on what service you require. Please see the various options below:

Full Contracting – We provide a full contracting service which includes the supply, hire, installation, and dismantling of the system in one price per m2 for a set time period*. JMAC will manage the allocation and movement of materials on site, leaving all work areas clean and tidy before vacating site. Our trained supervisors will visit site to ensure the standards are maintained. We provide this service within the NE, NW or within one hour of our Stockton On Tees depot. However, we work with a selective group of strategic partners who are based around the UK who can offer the service levels required – Please get in touch and we will recommend the closest one to you.

*Additional hire charges are incurred per week thereafter, should the hire time be exceeded. 

Hire only – We will deliver allocated materials to site specific to your needs. On delivery we will train your workforce/operatives on how to erect and dismantle the Macdeck System safely, and how to store and manage the equipment. A Macdeck certificate is issued once the trainer has evaluated competency levels. Price will be based on a weekly hire rate per m2 and we will collect the kit upon project completion.

Labour only** – If you have purchased or hired our Macdeck system, we can provide a labour only option where our fully trained Macdeck installers will attend your site to erect/dismantle and safely store the system.

Hire and Labour** – A set allocation of materials will be delivered to site. On delivery, the hire will commence for the agreed duration. This acts as the hire element of works.

In geographical areas or specialist jobs where JMAC can provide labour, a fixed labour cost will then be agreed to run alongside the hire agreement. This hire/labour option will provide the client with a supply and fit service undertaken by our knowledgeable and experienced install teams.

Purchase – Our Macdeck system is available to purchase either Mac branded or Bespoke branded (with your company logo). Prices are subject to volume, location and minimum order quantities where applicable.

JMSS products that are available to purchase with our Bespoke branding service:

Macdeck Legs

** This option is dependent on location or specified jobs, we currently provide this service in NE, NW, Cumbria & South Scotland. We’re constantly growing and evolving, so we always try to be flexible with our clients – If you would require this service but your location is not listed, please give us a call to see how we may be able to assist with this.

What is the process should JMSS be successful in securing tendered works?

We will attend a pre-start meeting between the client and our experienced operations team. This meeting will discuss your project programme, time frames and needs, you will receive our operations & maintenance manual, RAMS, booking in procedures training manual, and other supporting documentation. Going forward from this, you can then book in your first plots with our operational admin team and our trained installers will attend site as and when required.

How do I use your booking in service for my project?

A specific service is tailored to the needs of each client, you can email info@jmacsafetysystems.co.uk or call our office on 01642 563696.

Is there evidence that work has been completed?

Upon each erection and dismantle, a handover certificate is signed by the JMAC installer and a member of the site team. This handover certificate is a legal document to provide proof that, at handover stage, the system is fit for purpose and in safe working order as per manufacturers guidelines. A copy of this handover is retained onsite for their records and a second copy is returned to the office for payment evidence.
