STEP 3: Clamp Armour/Braid
Slide middlenut up to entry and hand tighten.
If not already screwed into equipment, grip the entry with a spanner/wrench.
Use a second spanner/wrench to tighten half to three quarters of a turn.
STEP 4: Inspect Armour/Braid
Unscrew the middlenut . The armour clamp ring should now be locked in place.
Visually inspect that the armour/braid has been successfully clamped between the spigot 
and the armour clamp ring .
If clamping is not satisfactory, repeat step 3.
STEP 2: Prepare to Clamp Armour/Braid
Slide Entry over cable.
STEP 1: Fit Armour To Spigot
Slide spigot over cable.
Push armour/braid up to spigot shoulder.
Slide clamping ring up to the armour/braid by hand.
NOTE: Support the cable to prevent it twisting. To aid wiring inside the enclosure, it
may be beneficial to strip the inner sheath as shown above.

STEP 5: Reassemble
Replace entry .to enclosure. If required, use the appropriate IP washer.
With inner seal properly seated into the entry, tighten up the middle nut by hand.
Using a wrench/spanner tighten a further 1/6 turn.
STEP 6: Install Backnut
Tighten the backnut until a seal is formed around the cable.
Use a wrench/spanner to grip the middlenut .
While preventing the middlenut turning, use a second wrench to apply one further full turn to the backnut .
STEP 7: Inspect Backnut
Use the middlenut guide as an indication that the backnut is in the correct position to suit cable diameter.
A diameter scale below is provided to assist this process.
