Page 6: Installation Clearances
Installation clearances Standard side-room vs. Restricted side-room The standard side room requirement is 550 mm. If less than this is available, it is possible to shorten the secondary arm (the one that attaches to the gate). Do not shorten it to less than 350 mm. Take care that the attachment point between the gate and the secondary arm does not foul on the output shaft. - Page 7 This is useful where the gate must open further than 90 degrees, or where the gate must open out- wards. Contact Merlin for side-mounting covers. Out-swinging gates This also requires side-mounting covers. It may be necessary to fabricate longer primary arms for some installations.
