1. See the A77P, A77Q and A77R series of Standard Plans for typical use of End Anchor Assembly (Type SFT-M).

2. For details of the anchor plate and 3/4" cable, see Standard Plan A77S3.

3. A 6'-0" length steel foundation tube, TS 8" x 6" x ¾6", without a soi I plate, may be furnished and installed in place of the 4'-6" length steel foundation tube ond soil plate shown. Minimum embedment of the 6'-0" length tube shal I be 5'-9". A %" ¢ Hex head bolt and nut shal I be installed in the hole in the 6'-0" length tube to keep the wood post from dropping into the tube.

4. Place End Cap Type B when pedestrians, bicycles or traffic is within contact of the troi I ing end of the exposed element or rail element may be cut 1" past the end of the post. CI eon, treat and cut off sharp edges.

5. Increased clear distance behind the roil is required from 50' prior to the lost post of the End Anchor Assembly (Type SFT-M). Beginning at 50' upstream of the last post of the End Anchor Assembly, the required clear distance increases to 5' at post No. 5. From post No. 5 to the last post of the End Anchor Assembly, the required clear distance increases at a rate of 1.5' for each post.

6. Dike with a maximum height of 4" may be placed under or in front of the End Anchor Assembly (Type SFT-M).

If the anchor posts are in conflict with the 4" high dike, the I ast 25' of ra i I may be tapered back a maxi mum of 1 '-0" to al low the dike to maintain alignment.
