Consisting of Aluminium or Stainless Steel bases with a Stainless Steel strap complete with a tensioning clip the BICON Multicleat system offers the best flexibility for cable fixing available on the market today. With an unprecedented test portfolio and service record, the BICON Multicleat system should be your first choice for trefoil and single cables installations requiring a high system fault current rating.

Multistraps are used as intermediate restraints and are positioned centrally between a pair of Multicleats. The standard and heavy duty products have different short circuit ratings related to their installation spacings. Please consult the following information in order to make the correct selection.

All Multicleats and Multistraps now come with a disposable shear torque tensioning adapter. This was introduced in response to customer requests to improve the closure of the cleats and also better control the tension applied during installation. The adapter fits into the open end of the winding pin and is used with a standard 13mm socket wrench. Thus simplifying installation. When the correct tension has been applied the adapter shears off LSOH material liners are available for both the Multicleat and Multistrap. The LSOH conform to BS6853. Please contact the technical team who will be able to offer the correct advice to suit your individual installation.

Installation Sequence

Fasten base to support with M10 fixings. Loop strap through base and around cables. Standard duty = 2 loops. Heavy Duty = 3 loops	Pull slack into outer loop. Insert split pin from right hand side around outer layer of strap about 10mm from end. Push plastic shear torque adaptor fully onto the end of the split pin and attach 13mm socket wrench. To tension the strap rotate key anti-clockwise with the socket wrench until the adaptor shears.	Remove the shear torque adaptor and wrench. Swing the key over and engage in slots in clip.

Multicleat / Multistrap Selection and Spacing for Fault Current Rating

Multicleat / Multistrap	Spacing 'b' m Max	Short Circuit		Cleat Spacing at vertical change of direction (mm)
		Current kA
		rms	peak
Standard Duty	1.8	43	114	300
Heavy Duty	1.5	50	130	300
Heavy Duty	1.2	71	184	300
Important note: To ensure adequate restraint, Multistrap MUST be used at the mid-point between cleats on all horizontal and vertical straight runs.
Horizontal changes in direction, restraint spacing of 300mm maximum. Use Multistrap and/or Multicleat, as appropriate, to suit support structure.

Two Bolt Type: AB, AD and JB	Single Bolt Type: PF
Base Thickness 11mm	Base thickness 6mm
In all applications the Multicleat bases should be fixed with either one or two M10 fixings as appropriate
