NOTE: A socket wrench or socket attachment on a drill is needed to loosen and remove bolt from lid.
BOLT RING CLOSURE FOR OPEN HEAD DRUMS
1. Check gasket to ensure cover gasket is properly fitted into cover groove. (See Figure 1 or 2)
2. Place cover on drum, being careful to properly seat gasket fully around curl. (See Figure 3)
3. Position and seat ring with lugs downward. Ensure inner channel of closure ring engages entire drum curl and
cover. (See Figure 4) Apply downward pressure on cover. Use a non-sparking dead-blow mallet to further seat
cover and drum curl into the inner channel of the ring.
4. Insert bolt through the unthreaded lug of the ring. Assemble the locking hex nut onto threaded end of bolt and
tighten into threaded lug. (See Figure 5) Close ring to an initial gap of about 1/2".
5. Tighten bolt with a calibrated torque wrench while using downward pressure on cover and hammering the
outside of the ring with a non-sparking dead-blow mallet to further seat the ring. Continue tightening and
hammering the ring until the torque stabilizes at 55-60 ft-lbs and does not decrease when further hammering on
the ring circumference is performed. Ring ends must not touch.
NOTE: Effective 25 September, 2006 and in accordance with CFR 178.2(c), we have revised this procedure
to use torque as the most effective closure requirement.
6. Lock ring by tightening nut against unthreaded lug. (See Figure 6)
