Slough fielded a changed side for the trip to Hendon with Dan Cann and Leigh Mason returning to the starting line up.
Hendon had the first opportunity of the game after nine minutes. Rene Street's header was helped on its way by Eugene Ofori. The effort beat Parkin but Hodges was on hand to clear off the line. Ross Pickett should have done better when setup by Ofori, but after scoring twice in the previous game, could not find the target as he scuffed his shot wide.
Slough's first chance came as Matt Murphy met a Josias Carbon corner, but could not get his effort on target as the ball flew wide.
Ofori, Hendon's most dangerous player in the opening half, setup Frendo, another of the goalscorers from Tuesday night's win for the Greens, but similar to Pickett, Frendo could not hit the target when well placed.
Slough had a good opportunity as the end of the half. A low drive from Christian Metcalfe was not held by Dave King and Dan Cann followed up but could not make sufficient contact with the ball and King was able to recover. Slough should have taken the lead moments later. Matt Murphy saw his effort parried out by King, Cann then saw his effort blocked and the ball fell kindly to Leigh Mason. With much of the goal to aim at, his effort struck the bottom of the post and bounced harmlessly away towards the corner.
Frendo had a good opportunity with sixty two minutes gone. The ball fell to the striker having bounced off Parkin and despite being under pressure, Frendo went for power rather than placement and fired over the bar.
Bradley Bubb was introduced for the home side and nearly had a goal on his debut. His fierce drive took a nick off Steve Daly which took it just wide of the angle.
Slough finished much the stronger of the two sides despite this being their fourth game in seven days but could not make their pressure count. Michael and Matt Murphy both had chances but were easily saved by King and Slough had to settle for a point.
Slough will be looking over their shoulders at the relegation spaces, but one more win will ensure their Premier Division status for next season.
