Johnny B. Straight utilizes a master control stake that fits directly under the unit. The master stake is approximately 28 inches in length and two inches in diameter. It has a hole drilled through the top to accomodate a control rod or shackle that links the base to the master stake. It is this linkeage that prevents the unit from being moved in a direction that would enable tipping.
The master stake is first emplaced by sledge hammer or by pre-drilling the soil, which may be necessary with hard or frozen soil. The portable toilet unit may then be dragged over the control stake and the control rod attached as described below. Movement of the unit from side to side, or forwards and backwards, is prevented due to the denial of leverage.
The picture in the link below shows how the Johnny Jr. unit works using a 3/8 inch configuration (a one half inch configuration is used with Johnny B. Straight):
Using a wood boring or similar bit, drill 1/2 matching opposite holes in each leg of the base approximately eight to twenty inches from the end facing the utility pole. The choice of hole sets will be determined by the terrain on which the portable toilet is situated. There are five half-inch holes on either side of the unit for the Control Rod. The choice of which hole to use is based on terrain requirements and the need to avoid ballast cells in the bases of some plastic units. The two larger 5/8th inch holes at the top of the unit are for ground staking with rebar or with the stakes provided in the Johnny Upright Deluxe model
Secure Johnny Upright to utility pole, fence, framing or other stationary object.
Insert control rod through one 1/2 hole in base and insert through matching holes in Johnny Upright. You may wish to use several small lengths of 2x4 to temporarily elevate unit, so as to be able to match drilled holes with the predrilled holes in the Johnny Upright Unit.
Make sure unit and toilet is approximately level. Secure control rod with 1/2 washer and then tighten the 1/2 hex nut with a wrench. For extra security use a cotter pin or a small lock (Master Lock size 130D or the Master Lock 630D combination lock are recommended) inserted through the hole at the end of the control rod.
Ground Staking: If you are going to ground stake the unit with rebar then you should select a length that will provide additional tipping protection to the back (typically four to five feet depending on soil conditions—enough to leave about three feet of rebar extending straight up from the ground to protect against back tipping). The unit should be positioned as close to the rear of the portable toilet as possible to allow the stakes to give this additional protection should it be needed. Do not drive the rebar so close to the level of the staking holes that it could be lifted off the Johnny Upright unit. An “L” shaped bend made at the top of the each piece of rebar will provide additional lift off protection.
For best results, Johnny Upright should be used on level ground but it can also be used effectively on a variety of uneven surfaces. (An “H” unit for ground staking is available for additional protection against back tipping.) The unit is designed primarily for use with a pole with staking as an emergency option.
