Why use the Compact Perforated Bar Servery Shutter?
The RA4 Roller Shutter is one of our most popular roller shutters, as it uses a compact shutter box and guides, providing a neat solution and high security. The perforated lath, has lots of small holes punched into the laths, which provide 18% vision. The perforated laths are ideal when you need vision/air flow but still need to maintain a higher level of security. The shutter can be supplied with a fully perforated curtain, can be mixed with Solid Laths to provide extra security. For extra security, the perforated laths can have Poly-carbonate inserts. If you need more vision then we have a Punched Laths available, that provides up to 44% vision.
The Compact Perfroated Bar Servery Shutter is available Manual Operation - Belt Winder, Rod Crank and Spring and Lock. Why not automate the shutter, to make daily operation easier and you can incorporate your shutters into a fully automation system, including Timers, Remote Control Systems and Home Hubs eg; Alexa.
The Compact Perforated Bar Servery Shutter comes powder coated as standard in White, Brown, Black or Cream as standard. The shutter can be Powder Coated any BS or RAL colour to match your colour scheme.

The RA4 is available both manually and electrically operated using a tubular motor inside the barrel. The options priced are shown on your quotation which also shows the method of operation we have included. This list shows possible options which would incur different costs.
SWIVEL BELT WINDER - for shutters up to 15kg
This type of operation is used when the roller shutter is fitted on the outside of the property and is lowered/raised using the Swivel Belt Winder from the inside. The grey belt is pulled up and down to lower and raise the shutter. The swivel winder coils the belt when it is pulled to open the shutter. The belt is 14mm wide and grey in colour and a guide tube to protect the belt through the building wall. The shutter locks by using the locking spring which connects the curtain to the barrel and lock out in the back of the shutter box.
GEARED BELT WINDER- for shutters between 15kg and 25kg
This is the same as the Swivel Belt Winder but uses a crank handle to raise and lower the shutter. The Geared Winder works at 1:3 ratio with removable handle. The shutter locks by using the locking spring which connect the curtain to the barrel and lock out in the back of the shutter box.
ROD CRANK OPERATION - for shutters up to 25kg
This type of operation is usually on windows where the shutter is external and is operated internally using a geared rod crank handle which hangs vertically and secures into a clip when not in use. The shutter is lowered and raised by turning the handle in a clockwise or anti clockwise direction. The shutter locks by using the locking spring which connect the curtain to the barrel and lock out in the back of the shutter box.
Roller Shutters usually installed mainly over doorways or Serveries are raised up and down by lifting and lowering the curtain by hand. The roller shutter has a spring in the barrel which helps lifting the shutter. As standard a central bottom lath lock is provided which has a key in the bottom lath and bolts shoot into the guides rails at each side. The Bottom lath lock can be operated from both sides but has a secure and non-secure side to the lock. Optional bullet locks are available which are pins that go through the guide rails each side.
ELECTRIC - (N.B. minimum shutter width 750mm)
Electric shutters are usually fitted on larger openings where Manual Operation is not suitable or where the operator requires an easy, clean and user friendly type of operation. Single phase tubular motors are enclosed within the barrel giving full protection from the elements. Electric Roller Shutters can be controlled individually or grouped to one controller. The controllers available include internal rocker switch, security key switch or Remote Control. Manual overrides are available on Electric Roller Shutters which allow the shutter to be operated when the power to the shutter has failed.
